Description

Method and application for improving wear resistance of metal materials

The invention belongs to the field of metal material processing, and particularly relates to a treatment method and application for improving the wear resistance of a ferromagnetic metal material. Background technique

How to improve the anti-wear performance of metal materials has always been an important research direction in the field of materials engineering. The current approaches include transforming material formulations and treatment methods.

In the treatment mode, the heat treatment can effectively improve the wear resistance of the metal material and is widely used. However, due to the residual stress and incomplete phase transformation caused by the heat treatment process, it is difficult to maximize the wear resistance of the metal material; in addition, the deformation, oxidation and burning of some elements introduced during the heat treatment process make the heat treatment not be the final process. It limits the scope of use. Summary of the invention

In order to overcome the residual stress and incomplete phase transformation generated in the existing heat treatment technology and the deformation, oxidation and burning of some elements introduced by the heat treatment process. The invention provides a new metal material processing method and application, which reduces the residual stress on the basis of the metal heat treatment, reduces the degree of incomplete phase transformation, and has no deformation, so that the wear resistance of the part is greatly improved. Has a wide range of applications.

The invention is implemented by the following technical solutions:

Fix the processed part on the fixture, connect one end of the fixture to the ultrasonic transducer, place the fixture of the fixed part and the ultrasonic transducer into a high-frequency electromagnetic induction coil, and then install the parts and cards. The high frequency coil with the ultrasonic transducer is placed in a low frequency excitation coil.

In operation, three parts of energy are simultaneously received in the workpiece to be processed: the first part is the magnetic energy from the low frequency excitation coil, the second part is the electric energy induced by the high frequency induction coil in the workpiece, and the third part is from the ultrasonic transducer. Mechanical energy. The specific technical solutions are as follows:

In operation, you can select the appropriate ultrasonic and high depending on the workpiece to be processed and the type of material. Operating parameters of the frequency coil and the low frequency excitation coil. The better parameters are:

The first part of the equipment and parameters that generate magnetic energy: Excitation power is produced by Beijing Witten Company, model is

RJ-50, the number of low-frequency excitation coils is 100~500匝, and the excitation power supply is directly connected to the excitation coil by wires to generate the required magnetic field. The range of parameters to be processed is: AC current peak current 30~80 amps, frequency 10~50Hz.

The second part produces equipment and parameters for induction energy: The induction power supply is produced by Shanghai Tengchang Co., Ltd., model GP26, the induction coil is 3~10匝, and the output end of the induction power supply is connected to the induction coil to generate the required Induced current. The range of parameters to be processed is: Frequency 10~100KHz, output power l~8Kw.

The third part of the equipment and parameters for generating ultrasonic energy: using the GC-5025 ultrasonic transducer produced by Wuxi Huifeng Company, the output power is 110w, and the ultrasonic power supply is provided by Zhangjiagang Feibo Ultrasonic Power Supply Factory. Processing parameters are: Output power 20~110w, frequency 10~30KHz. The output end of the ultrasonic transducer is attached to the fixture with screws and epoxy glue.

After the workpiece is fixed on the fixture, the low-frequency excitation power supply, the high-frequency induction power supply and the ultrasonic power source are simultaneously turned on, and after a certain period of work, the processing of the workpiece is completed. The general treatment time is 35 s or more, preferably 35 s to 500 s, and most preferably 100 s to 500 s.

Under the combined action of magnetic field and current, the ferromagnetic metal will simultaneously produce magneto-plasticity and electro-plasticity, which will lower the barrier of high-energy to low-energy motion in the material, and the effect will be beneficial to the reduction of residual stress and unstable phase. The transition of the steady phase, while the applied ultrasonic energy promotes the degree and efficiency of this motion process, the residual stress is reduced more, and the transition of the unstable phase is more thorough. These two processes make up for the deficiencies in the heat treatment process, significantly improve the wear resistance of the metal materials, and in particular, significantly improve the wear resistance of the ferromagnetic metal materials, and the service life of the workpiece is remarkably improved. The metal material processing method of the present invention can be widely applied to metal material processing in the fields of the electronics industry, the machining industry, the mining industry, the construction industry, and the automobile industry. Especially for printed circuit boards (PCB) drill bits; carbide inserts, milling inserts, drill bits, twist drills, milling cutters; high speed steel taps, broaches, gear hobs; high chromium steel Grinding ball; surface carburizing gears and other applications have obvious effects.
