Dry Sliding Wear Behaviour of Al₂O₃ Coatings for AISI 410 Grade Stainless Steel

Abstract:

The wear and corrosion resistance of working surfaces can be improved by applying suitable coatings using thermal spray techniques. In the present work air plasma spray deposition technique (PSD) was used to coat Al₂O₃ ceramic powder on AISI 410 grade stainless steel. The steel substrate was primarily coated with Ni/Cr which acts as a bond coat for good fastening. Surface morphology of Al₂O₃ particulates of the coating was examined by scanning electron microscope (SEM). Uniform distribution of the Al₂O₃ particles on Ni/Cr pre-coated steel substrate was observed. Sliding wear tests under dry condition were conducted for different sliding velocity by keeping applied normal load and sliding distance constant. The results indicate significant improvement in the wear resistance of Al₂O₃ coated stainless steel substrate using PSD. The micro hardness of Al₂O₃ coated surface was found to be higher than that of the base metal.
