Thermal spraying zirconia coating improves the wear resistance of equipment

Conventional use of chromium plating has a certain protective effect on the surface of the piston rod, but it is found that the surface of the piston rod is still severely worn after 1-2 years. The chrome layer around part of the worn area has peeled off and the peeling area is severely corroded, and the coating is locally corroded. This is because the chromium plating layer is thin and has insufficient hardness and wear resistance. It is easy to wear and even wear. The chromium layer has hydrogen-induced cracks, and rust occurs directly on the surface of the substrate. Corroded and peeled off.

 

 

Thermal sprayed zirconia coating is one of the coatings more suitable for strengthening the surface of piston rod due to its excellent wear resistance and corrosion resistance, and it can be prepared by thermal flame spraying technology. The surface of the piston rod forms a dense coating and adheres well to the substrate. Analyzing and analyzing the preparation and performance of thermal sprayed zirconia coating has positive significance for the application of coating on the surface of piston rod.
