Problems solved by technology

[0002] The friction plate of the clutch is made of asbestos, metal wire and other materials. With the increasing power, speed and load of the car, the operating conditions are increasingly harsh, and higher requirements are put forward for the performance of the friction plate; when working for a long time or Under extreme working conditions, faults such as fracture, slip, ablation and plastic deformation of the friction plate surface caused by abnormal friction are prone to occur. Research shows that the durability of the friction plate has an important impact on the performance of the clutch and even the entire vehicle; therefore , inventing a method that can effectively enhance the durability of clutch friction plates is of great significance to the development of the automotive field

Abstract

The invention belongs to the technical field of automobile parts, in particular to a treatment method for enhancing the durability of clutch friction plates. Take out, steam treatment, take out to get the pre-treated clutch friction plate; (2) microwave the pre-treated clutch friction plate for one time, immerse it in the coating solution for 8~10min, take out, second microwave dry treatment, take out, vacuum treatment The treated clutch friction plate not only has a sufficiently high and stable friction coefficient, the difference between the static friction coefficient and the dynamic friction coefficient is reduced, and the friction coefficient basically does not change with the external conditions, and has good thermal conductivity, large heat capacity and good performance. High temperature mechanical strength, and has good wear resistance and anti-adhesion, not easy to scratch the surface of the counterpart, low noise and vibration, effectively ensuring the reliability of the clutch friction plate transmission system.
