A typical structure of thermal spray coatings consisted molten particles, semi-molten oxides, pores, and cracks. These factors caused the porosity sprayed coatings, leading to a significant influence on coating properties, especially their wear-corrosion resistance. In this study, post-spray sealing treatment Cr3C2-NiCr/Al2O3-TiO2 plasma-sprayed was carried out, then, corrosion properties were ...

WC-based cemented carbides were prepared by spark plasma sintering (SPS) of WC-Co-Cr3C2-VC alloy powder adding different contents graphene. The phase composition, microstructure, mechanical properties, and magnetic properties carbide investigated means XRD, SEM, Vickers hardness fracture toughness tests, tests. results showed that the specimens show a trend first increasing then decreasing with...
