Description
Technical Field
The invention relates to the technical field of stainless steel surface treatment, in particular to a treatment process for stainless steel plasma polishing and PVD coloring.
Background
Stainless steel is short for stainless acid-resistant steel, and steel resistant to weak corrosive media such as air, steam and water or having stainless steel is called stainless steel; while the steel type which resists corrosion by chemical corrosion media (chemical immersion such as acid, alkali, salt and the like) is called acid-resistant steel, the corrosion resistance of the steel type is different due to the difference of the chemical components of the steel type and the acid-resistant steel, common stainless steel generally does not resist corrosion by chemical media, the acid-resistant steel generally has stainless property, the term "stainless steel" not only refers to one kind of stainless steel but also refers to more than one hundred kinds of industrial stainless steel, and each kind of developed stainless steel has good performance in specific application fields.
The surface treatment effect on the stainless steel has obvious influence on the stainless steel in rust resistance, corrosion resistance and scratch resistance, and polishing is the most critical step in the surface treatment of the stainless steel. The polishing is a processing method for reducing the roughness of the surface of a workpiece by using mechanical, chemical or electrochemical action to obtain a bright and flat surface, and is a modification processing of the surface of the workpiece by using a polishing tool and abrasive particles or other polishing media.
The traditional polishing method is mechanical polishing, wherein a polishing wheel is used for rotating on the surface of stainless steel, and certain pressure is applied to the surface of the stainless steel, so that high temperature is generated on the surface of the stainless steel due to friction, and a processing deteriorated layer is formed on the surface of an object to be polished, mainly manually. But the cost is high, the labor intensity is high, the working efficiency is low, batch polishing cannot be realized, meanwhile, the pollution is serious, and the color matching of the appearance of the stainless steel cannot be realized.
Disclosure of Invention
The invention aims to provide a treatment process for stainless steel plasma polishing and PVD coloring, which can remarkably reduce polishing cost by adopting plasma polishing, has no pollution, can be processed in batch, has high polishing efficiency and good polishing effect, can color the appearance of the stainless steel by adopting PVD coating so as to meet the requirements of people on the color and brightness of the appearance of the stainless steel, and has strong practicability.
The technical problem to be solved by the invention is realized by adopting the following technical scheme.
The invention provides a treatment process for stainless steel plasma polishing and PVD coloring, which comprises the following steps:
plasma polishing: polishing the stainless steel blank by using polishing solution, wherein the polishing condition is electrifying for 5-10min, heating the steam to 70-85 ℃, then cleaning and drying;
carrying out PVD coating: and coloring and coating the dried stainless steel product for 7-9 hours by adopting a target material, and then coating the film for 1-3 hours by adopting a nano coating to prevent fingerprints.
The treatment process for stainless steel plasma polishing and PVD coloring provided by the embodiment of the invention at least has the following beneficial effects:
the plasma polishing is that metal ions which are electrified and separated from a workpiece and polishing solution are adsorbed on the surface of the workpiece, the current impact at the bulge of the workpiece is high, the workpiece is quickly removed, the current flows, the unevenness is continuously changed, and the rough surface is gradually leveled. Plasma, also known as the fourth state of matter, is an electromagnetic gaseous discharge phenomenon that partially ionizes gaseous particles, such ionized gas comprising atoms, molecules, radicals, ions, and electrons. The plasma is that under high temperature and high pressure, the polishing agent is water-soluble, electrons can escape from atomic nuclei and escape under high temperature and high pressure, the atomic nuclei form positively charged ions, when the ions reach a certain amount, the ions can become a plasma state, the energy of the plasma state is very large, and when the plasma rubs with an object to be polished, the object can reach the effect of surface brightness in a hectare.
The PVD coating is to use a low-voltage and large-current arc discharge technology under vacuum conditions, to evaporate the target material by gas discharge and to ionize the evaporated material and the gas, and to deposit the evaporated material and the reaction product thereof on the workpiece by the acceleration of an electric field.
In the invention, plasma polishing is a composite reaction of gas discharge and chemical action, and does not directly contact with the surface of a part, so that microcracks and residual stress on the surface of stainless steel can be avoided, and the service life of the stainless steel is prolonged. The polishing solution adopts a low-concentration neutral salt solution, so that the polishing solution can be directly discharged, the wastewater generated in the polishing process only contains metal thrown away by plasma, the pollution is low, the polishing solution is more environment-friendly, the development direction of green manufacturing is adapted, and meanwhile, the metal in the wastewater can be recycled, so that the resource waste is avoided; can obviously reduce the polishing cost of the stainless steel and is beneficial to popularization. The polishing process can achieve the effect of electroplating the mirror surface within ten seconds or several minutes, the polishing efficiency can be greatly improved, a layer of passive film can be generated on the surface of the stainless steel after polishing, the stainless steel can keep durable and bright, the oxidation is effectively prevented, and the scratch resistance and the precision of the stainless steel are improved. The thickness of the PVD coating film is micron-sized, generally 0.3-0.5 μm, and the thickness of the decorative coating film is 0.3-1 μm, so that various physical properties and chemical properties of the surface of the workpiece can be improved under the condition of hardly influencing the original size of the workpiece, and no reprocessing is needed after coating. Meanwhile, the PVD coating can enable the binding force of the film layer and the surface of the workpiece to be strong, the PVD coating is more durable and wear-resistant, the diffraction performance of ions is good, the PVD coating is suitable for coating of workpieces with complex shapes, the deposition rate of the film layer is high, the production efficiency is high, the types of the coatable film layers are wide, the performance of the film layer is stable, and the safety is high.
By combining plasma polishing and PVD coating, the plasma polishing and PVD coating are mutually cooperated, so that the corrosion resistance and the scratch resistance of a workpiece can be improved, scratches and abrasion in the subsequent installation process are reduced, color mixing can be performed according to different applications, the brightness effect is kept, and the workpiece is more attractive.
