Oil seal wear ring is widely used in the sealing system of mechanical equipment, its main function is to prevent the leakage of lubricating oil and external pollutants into. Due to the harsh working environment, the oil seal wear-resisting ring often faces problems such as wear, corrosion and fatigue, resulting in equipment failure. Therefore, it is very important to improve the surface performance of the oil seal wear-resisting ring. The thermal spraying technology can significantly improve the wear resistance, corrosion resistance and fatigue resistance of the wear ring by depositing a special coating on the surface of the substrate.
The application of thermal spraying technology in the surface strengthening of oil seal wear-resisting ring is mainly reflected in the following aspects:
1, improve wear resistance: Through thermal spraying technology in the oil seal wear ring surface deposition of a layer of high hardness, high wear resistance coating, such as tungsten carbide (WC), chromium carbide (Cr3C2), can significantly improve the wear resistance of the wear ring, extend its service life.
2, enhance corrosion resistance: Spray a layer of corrosion resistance coating on the surface of the oil seal wear-resisting ring, such as nickel-based alloy, cobalt-based alloy, etc., can effectively prevent the corrosion of the corrosive medium on the matrix, improve the corrosion resistance of the wear-resisting ring.
3, improve the fatigue performance: Through thermal spraying technology on the surface of the oil seal wear-resisting ring to form a layer of good fatigue resistance coating, such as metal ceramic composite material, can significantly improve the fatigue resistance of the wear-resisting ring, reduce the failure caused by fatigue.
As an effective surface strengthening method, thermal spraying technology has significant advantages in improving the surface properties of oil seal wear-resisting rings. The wear resistance, corrosion resistance and fatigue resistance of the wear ring can be significantly improved by selecting suitable spraying process and materials. In the future, with the development of new spraying materials and the optimization of spraying process, the application of thermal spraying technology in the surface strengthening of oil seal wear-resistant rings will be more extensive and in-depth.
