Determination of Abrasive Wear Resistance of Plasma Sprayed Coatings on Stainless Steel Substrate

摘要

In this paper wear charecteristics of two different ceramic powder coated stainless steel has been determined. The thickness of 250 μm coatings were sprayed over the stainless steel substrate by Atmospheric Plasma Spray process. Two different types of coating materials such that Yttria Stabilised Zirconia, Zirconia Ceria powder were used. The abrasive wear charecteristics of Zirconia Ceria powder coated specimen was compared with Yttria Stabilised Zirconia. The results showed that the Zirconia Ceria powder coated specimen have greater resistance towards wear. It was found that the wear resistance of the material increases with an decrease in the surface roughness of the coating layer.
