the highest surface hardness was determined with the Taguchi program. The friction and wear behaviors of the coating, an … electrolytic hard chrome (EHC)-plated coating and IN718, were comparatively investigated via a reciprocating sliding wear test at ….02 at 450°C; the coating had the lowest FC among the three samples. At both temperatures, the coating wear depth (WD) was …
