Abstract

In this paper we studied the possibility of mechanical processing of a coating produced by atmospheric plasma spray method from nickel-based self-fluxing powder. Two samples were realized from the same alloy type - NiCrBSiFe alloyed with WC, one of which was mechanically processed in the raw state and the other after applying the self-fluxing treatment. Subsequently, their behaviour was observed during the mechanical processing. Both the morphology of the coatings after processing and their mechanical properties (using scratch method) were evaluated.
