Wear performance of graphene nano platelets incorporated WC-Co coatings deposited by hybrid high velocity oxy fuel thermal spray

WC-Co coatings have been used as wear resistant in aero engines for decades, and research is still ongoing to further improve the performance of these through compositional modifications reduce wear. The are unlubricated sliding protection compressor parts such as; compressor, disc mid-span stiffeners aerofoils. In this study, two different graphene nanoplatelets (GNPs) were introduced into (88–12 wt %) coating a hybrid thermal spray technique. Under correct injection conditions, HVOF leads in-situ powder mixing which eliminates need premixed powder. addition GNPs led an increase porosity coatings. Both improved system against alumina reduced damage counter surface. Against body, although few cases GNP incorporated had higher rate, lower deformation on bodies obtained. When surfaces combined, whole.
