Abstract: In the present piece of research work, plasma sprayed coatings of fly ashillmenite is deposited on mild steel substrate using a 40 kW atmospheric plasma spray system. Solid particle erosion tests are conducted at three different impact angles (i.e. at 30°, 60°and at 90°) using dry silica sand and silicon carbide as erodent. It is observed that, erosion rate is mainly dependant on angle of attack. The rate of erosion is also affected by the type of erodent. Microstructural observations reveal that the coating removal is mainly by chipping/plowing type mechanism at low impact angles. At higher impact angles (i.e. at 60° & 90°) the erosion wear behavior is as of the brittle material.
