Plasma spraying is one of the methods used for combating wear. Despite of its wide spread industrial use, little is known about the basic friction behavior and mechanism by which such coatings wear. In this work, the abrasive wear resistance of plasma sprayed ceramic coatings on Cast Iron substrate has been investigated through pin-on-disc test. It was found that the coefficient of friction and wear mainly affected by splats and porosity, surface roughness and coating thickness. The coefficient of friction is found to be more significantly effected by load than other test parameters.
