Abstract

This paper studies the influence of the substrate material on the phase composition, microstructure, microhardness, and wear resistance of Ni-Cr-BSi-WC (Ni95Al5) coatings. Three types of substrates were studied, AISI 5060 Steel, SAE J431 automotive gray cast iron, and Ti-6Al-4V. It has been found that in the as-coated condition the surface layers have a phase composition of crystalline ɣ-Ni solid solution, amorphous, Ni3B, CrB, and Cr23C6. There are different changes of the surface after 80 min abrasive wheel.
