Abstract
An investigation was conducted to explore the feasibility of applying plasm a spray ceramic (alumina) coatings to Hadfield manganese and mild steels. T he results suggest that an intermediate bond coat of Ni-Al alloy is necessa ry, for satisfactory, coating adhesion on both the mild and manganese steel substrates. The coating chemistry is altered by large scale diffusion of e lements from the substrate to the coating and counterdiffusion of elements from the coating into the substrate, both of which adversely, affect coatin g bond strength and abrasive were resistance.
