Definitions

  • the present invention relates to apparatus for pre-coating monofilaments of reinforcing materials such as silicon carbide or carbon fibres with a predetermined thickness of matrix metal by a process of physical vapour deposition, prior to consolidation of the coated reinforcement into a metal matrix composite material having substantially uniform fibre spacing.
  • the coating apparatus is operated under vacuum in a vacuum chamber.
  • the apparatus facilitates deposition of a matrix coating of sufficient thickness and uniformity that the desired matrix volume fraction is achieved for the finished composite without the requirement for any further matrix material to be added during the consolidation stage.
  • Suitable matrix materials include titanium or aluminium, or their alloys. Especially preferred are alloys of these elements which are capable of undergoing superplastic deformation.
  • the invention also relates to a method of producing a metal matrix composite material by consolidating pre-coated fibres produced by the apparatus. It is known to produce metal matrix composite materials from titanium alloy and long fibre reinforcements by a process which involves laying together the reinforcement fibres and thin foils of the matrix alloy. These are then consolidated using a regime which causes superplastic flow within the matrix material and subsequent diffusion bonding. This route to the product has two major disadvantages. Firstly, it is limited by the choice of matrix alloys because not all of these can be obtained commercially in suitable foil form. Secondly, control of fibre spacing is not always easily achieved across the full range of reinforcement to matrix volume ratios that might be desired.
  • matrix coating to describe matrix deposits of a depth sufficient to yield a desired level of matrix volume fraction, say at least 20 , when pre-coated fibres are subsequently consolidated.
  • matrix coated fibres This terminology will be used to distinguish the matrix deposits from coatings applied to fibres for other purposes, for example reaction barrier layers. Such coatings are much thinner than those required to provide adequate matrix material for a typical composite material.
  • the invention is a physical vapour deposition apparatus for pre-coating fibres of a reinforcement material with a predetermined thickness of matrix metal prior to consolidation to yield a metal matrix composite material having substantially uniform fibre spacing, the apparatus comprising:
  • heating means for heating a charge of metal in the or each evaporation crucible to a temperature at which an appreciable vapour pressure is generated and a flux of metal vapour is evolved;
  • a guide mechanism for guiding the reinforcement repeatedly through the vapour flux including means to effect twisting of the reinforcement about its longitudinal axis after each successive pass or after a predetermined number of passes through the vapour flux by an amount which is a fraction of 180°, thus exposing a different portion of the circumference of the reinforcement to the vapour flux and thereby improving the uniformity of the coating applied around the reinforcement.
  • the guide mechanism comprises two separate multi-pass transfer rollers and at least one twist roller.
  • the transfer rollers are positioned above the evaporation crucible(s) and spaced apart from each other with their rotational axes parallel. This enables the transferred filament of reinforcement to pass through the vapour flux as it moves between the transfer rollers.
  • the twist roller is positioned with its rotational axis inclined to that of the transfer rollers.
  • the twist roller is a multi-pass roller since this avoids the need for duplication of twist rollers.
  • the filament may be threaded around the rollers in a variety of ways. For example, it may be passed directly between the transfer rollers a given number of times before being routed once around the twist roller and then back to the transfer rollers. This cycle of a fixed number of passages between the transfer rollers, followed by routing once around the twist roller to effect reorientation of the filament, may be repeated as often as necessary to achieve the required depth of coating on the reinforcement.
  • twist roller The arrangement described here using a twist roller is particularly suited to the circumstances where the transport speed of the reinforcement through the apparatus is fairly slow. Slow transport speed means that a relatively thick coating of matrix material can be deposited at each pass. However, this could lead to matrix build-up and hence uneven coating of the reinforcement unless positive reorientation is effected.
  • the twist roller arrangement ensures that the reinforcement is twisted to a significant extent and enables substantially uniform coating to be achieved with a relatively small number of passes.
  • the transfer rollers themselves are responsible for the reorientation of the reinforcement about its longitudinal axis. Using this arrangement therefore dispenses with the requirement for a separate, inclined twist roller for effecting reorientation.
  • the transfer rollers are each provided with a series of circumferential grooves on their surfaces to guide the reinforcement through the apparatus.
  • the reinforcement is threaded onto the rollers in a figure-of-eight path, with one turn of the reinforcement occupying each groove in succession until all the grooves are filled.
  • This progressive threading arrangement inevitably means that the path of the reinforcement between the transfer rollers deviates slightly from the normal, with the result that unequal frictional forces are exerted on the periphery of the reinforcement by the sides of the grooves.
  • This unequal frictional contact causes slight twisting of the reinforcement so that, on its return path to the -other transfer roller, rather than being simply turned through 180°, the reinforcement presents a slightly different aspect to the vapour flux.
  • the evaporator prefferably comprises a cooled crucible and an electron beam gun arranged so as to heat the charge directly.
  • this arrangement enables a skull of solid material to be maintained at the interface between the charge and the crucible, thus minimising interactions between the molten charge and the crucible material.
  • An arrangement for continuous replenishment of the charge material is also desirable.
  • there is an elevating platform positioned underneath the crucible and the crucible has an opening in its base to admit a rod charge fed from beneath. This rod charge is raised by the elevating platform as the topmost part is consumed by evaporation.
  • a driven spool is a suitable form of the aforementioned powered take up-device for most situations. Otherwise a driven capstan could be used to pull the filament through the guide means especially if it is necessary to avoid tensioning the coated filament as it is wound upon its spool for storage.
  • the invention also comprises a method of producing a metal matrix composite material from matrix-coated fibres coated using the apparatus as claimed, which method comprises laying together a mass of such matrix-coated fibres and consolidating them by the application of heat and pressure to effect plastic flow within the matrix coatings and to cause fusion between adjacent coatings.

Here it is shown standing on the base member 1 of a vacuum chamber equipped with a flange 2. In use, flange 2 receives a vacuum chamber cover, but the cover is not shown in this view in order that the equipment contained within the vacuum chamber can be seen more clearly.
  • Base member 1 has a support framework 3 upon which are found the remaining parts of the apparatus, including two crucibles (4, 5) which each serve as a separate evaporator with a respective electron beam heater.
  • the electron beam guns are of a conventional form which is commercially available, though in the Figure only the exit slots 6 are shown. These guns are independently controllable so that appropriate melt temperatures can be maintained within the two crucibles.
  • Crucible 4 is intended to be used as the evaporator for the bulk ingredient of the coating material.
  • the coating material is a pure metal, or if it is an alloy having constituents with similar vapour pressures at the evaporation temperature
  • the second evaporator is not required because the coating material can be evaporated from a single crucible.
  • the coating material is an alloy having constituents with widely disparate vapour pressures at their respective evaporation temperatures, separate sources may be required in order to achieve a reasonable degree of homogeneity in the coating.
  • crucible 5 would be utilised when it is desired to introduce a small quantity of an alloying ingredient into the coating which ingredient has a significantly different volatility from the main phase or phases of the coating.
  • Crucible 5 is not provided with an elevating platform for charge replenishment, the whole of the crucible charge being provided within the crucible at the commencement of the coating process.
  • a shutter 9 (see Figure 2) is provided above each of the crucibles so that the charges may be pre-heated by the electron guns before the charge vapours are permitted to impinge upon the reinforcement to be coated.
  • the apparatus includes a supply spool 11 from which the reinforcement to be coated is drawn, a powered take-up spool 12 which serves to draw the reinforcement through the coating apparatus and upon which the coated reinforcement is accumulated, and a guide mechanism serving to guide the reinforcement in an appropriate manner over the top of the evaporators through the vapours from the evaporated charge material.

  • the functional interrelationship between the various components of the apparatus can be seen more clearly with reference to Figure 2.
  • This figure also illustrates schematically the vacuum chamber (designated 20), shutter 9 and an electron beam gun designated 21, which features are omitted from Figure 1 for clarity.
  • Figure 2 also shows a screen 22 which is used to protect the moving parts of the apparatus from unwanted deposition of metal vapours.
  • the manner of operation of the guide mechanism may be ascertained by reference to Figures 2, 3 and 4.
  • the reinforcement to be coated is drawn from the supply spool 11 and passed around transfer roller 13. It is then routed around transfer roller 14 and returned around transfer roller 13. This passage is repeated once more and on the second return of the reinforcement to roller 13 it is passed around twist roller 15 and then returned to roller 13 before resuming the former path between rollers 13 and 14. This cycle is repeated until there have been four coating stages and three changes in orientation of the reinforcement brought about by transit around the twist roller 15- This ensures that each quadrant of the reinforcement is presented in turn to the coating vapours.
  • the way in which the twist roller 15 functions is illustrated with reference to Figure 4.
  • the reinforcement Assuming that the reinforcement describes a circumferential path around one of the rollers, regardless of whether it is one of the transfer rollers or if it is the twist roller, then it maintains its surface orientation with respect to the peripheral surface of that roller. In effect, the reinforcement is turned upside down because there is no lateral inversion or twisting of the reinforcement with respect to the rotational axis of the roller. However, passage of the reinforcement around the twist roller changes the orientation of the reinforcement with respect to the rotational axes of the transfer rollers because of the angle at which the twist roller is inclined. A twist roller inclination of 45° causes the reinforcement to present a different quadrant to the coating vapours during the next series of direct transfers between transfer rollers following exit from the twist roller.
  • a sequence of three excursions to the twist roller during the repeated passages over the vapour source is thus sufficient to provide exposure of all four quadrants to the coating vapour.
  • the filament to be coated is drawn from the supply spool 11 and routed through the apparatus in the manner previously described. Then the evaporator is loaded with adequate charge material before the vacuum chamber is closed and evacuated to a suitable pressure, for example 10" 6 Torr. With the shutter 9 n place, the charge material is heated by operation of the electron beam guns until it is judged that equilibrium between the vapour and source compositions has been obtained. When this condition is achieved, the shutter is withdrawn and the vapour is allowed to flow towards the filaments to be coated. At this point the take-up spool 12 is started. Under typical operating conditions the reinforcement can be coated at a rate of about 20 metres per hour.
  • the inventors have produced metal matrix composite materials using silicon carbide fibres pre-coated with a deposit of titanium/65. aluminium/4 ⁇ vanadium alloy matrix material.
  • the fibres thus-coated were consolidated by canning a bundle of the fibres, evacuating and sealing the can, and then hot isostatic pressing (HIP) the canned material under pressure of argon for a period of two hours.
  • the HIP conditions were 150 MPa pressure and a temperature of 92 °C.
  • Similar matrix-coated fibres may be consolidated to form metal matrix composite materials by other methods provided that conditions of pressure and temperature are such as to cause adequate plastic flow in the matrix coating to close all interstitial spaces to a sufficient degree, and to cause adjacent matrix surfaces to bond to one another by a diffusion bonding mechanism.
  • Shaped products can be produced, for example by filament winding the matrix-coated fibres upon a mandrel, or by compaction of a mass of the fibres within a shaped die or between press platens. The consolidation is best performed under vacuum to avoid contact with contaminating gases which might inhibit the diffusion bonding of matrix material or otherwise adversely affect the material.
  • the apparatus as claimed can be utilised to coat a wide variety of monofilamentary reinforcements suitable for metal matrix composite products. Moreover a wide variety of matrix materials can be used as coatings by deposition from the vapour. To date, the inventors have experimented with the deposition of pure titanium, titanium based alloys, aluminium, aluminium based alloys and intermetallic materials such as titanium aluminides.

Abstract

Les fibres longues de renforcement, par exemple d'un matériau céramique, destinées à être consolidées pour l'obtention d'un matériau composite à matrice métallique, sont pré-enrobées d'unmétal matriciel grâce à un procédé physique de dépôt en phase gazeuse au moyen d'un appareil permettant de guider les fibres à travers un flux de vapeurs métalliques plusieurs fois selon diverses orientations. Selon un premier mode de réalisation, l'appareil comprend deux rouleaux de transfert à passages multiples (13, 14), situés de chaque côté du vaporisateur, et un rouleau de torsion (15) qui est incliné par rapport au plan des rouleaux de transfert. Selon un autre mode de réalisation, la réorientation des fibres est accomplie sans recours à un rouleau de torsion séparé grâce à des rouleaux de transfert comprenant des cannelures permettant de conférer une légère torsion au renforcement lorsque celui-ci quitte la surface du rouleau. On décrit également la consolidation des fibres, enrobées à l'aide de l'appareil, servant à former un matériau composite à matrice métallique grâce à l'application de pression et de chaleur, de façon à provoquer l'écoulement plastique et la fusion du matériau matriciel.
