Thermal spraying is a surface engineering technology that heats the material to a molten or semi-molten state through a high-speed flame or plasma flow, and then sprays it onto the surface of the workpiece to form a coating. In the application of inner and outer sleeves, thermal spraying technology is often used to improve the wear resistance, corrosion resistance and high temperature resistance of the sleeves, thereby extending the service life of the sleeves and improving the reliability of mechanical equipment.The basic steps of thermal spraying inner and outer sleeves include:
1,Surface preparation: Make sure that the sleeve surface is clean and free of oil, rust or other contaminants.
2,Spraying material selection: Select appropriate spraying materials such as tungsten carbide, aluminum oxide, etc. according to the working environment and performance requirements of the sleev
3,Spraying process: Use supersonic spraying equipment to evenly spray the selected material onto the sleeve surface.
4,Cooling and curing: The sleeve after spraying needs to be properly cooled so that the coating can solidify to form a solid protective layer.
5, Post-processing: After the coating is cured, subsequent processing such as grinding and polishing may be required to achieve the ideal surface roughness and flatness.
Technical points include:
-Coating thickness control: The coating thickness needs to be precisely controlled to ensure the normal operation of the sleeve and extend its service life.
Coating quality inspection: The coating should be free of defects such as peeling, sand holes, pores, cracks, etc. to ensure good bonding between the coating and the substrate.
Advantages of thermal spraying inner and outer sleeves:
Improve wear resistance: Thermal spray coating can significantly improve the wear resistance of the sleeve and reduce wear.
Enhance corrosion resistance: The coating can resist the erosion of a variety of chemicals and extend the service life of the sleeve.
Improve high temperature resistance: The coating can withstand high temperature environments and maintain the stability of the sleeve.
Cost-effectiveness: Compared with replacing the entire sleeve, thermal spraying has a lower maintenance cost and can quickly resume production.
Actual cases show that supersonic spraying of tungsten carbide coatings on inner and outer sleeves can effectively reduce the wear of the journal, improve the performance of the sleeve, and save production costs. In addition, the application of thermal spraying technology in the fields of metal green remanufacturing and additive manufacturing is becoming more and more extensive, showing its important position and potential in modern manufacturing.
Besides，we also offer Ceramic Coated Wear-Resistant Stainless Steel Shaft Sleeve for Slurry Pump Applications and Custom High Precision CD4/316ss Stainless Steel Shaft Sleeve for Pump Systems.
