Wear-Resistant Carbide Bushings Customized

The bushings are customized products according to the drawings:
Base material: stainless steel 304, stainless steel 316, carbon steel, 45# steel optional.
Second, the coating design: support customers to customize the production of drawings, according to the actual size of the bushing, the demand for working conditions to adjust the coating thickness (usually 0.1-0.3mm) and surface roughness, to ensure that the production of spraying and manufacturing can be installed directly after the use of the machine without the need for secondary processing.
Third, the choice of coating materials:
1、Can choose to surfacing Stellite alloy or spraying tungsten carbide coating
2、The combination process of Stellite alloy and tungsten carbide coating can be used to take into account the strength of the substrate and the wear resistance of the surface, avoiding the deformation and spalling problems caused by traditional welding or plating.
3, optional ceramic coating: ceramic chromium oxide chromium carbide coating (with corrosion resistance and high temperature advantages 800-1000 ° C, can be mirror processing), ceramic alumina coating (with corrosion resistance and high temperature)
Fourth, finishing:
1、Roughness after grinding: Ra0.8 
2、Roughness after fine grinding and polishing: Ra0.02
