Dependence of wear behaviors of hardmetal YG8B on coarse abrasive types and their slurry concentrations

► Using a modified wet sand rubber rimmed wheel test system ASTM B611 to evaluate the abrasive wear behavior in drilling fluids. ► Three kinds of coarse angular sands, SiC, Al2O3 and SiO2, of different hardness were used. ► Extremely long sliding distance experiment condition was built, which was up to more than 60 km. ► Different abraded areas of the hardmetal have different wear mechanisms. ► New wear model was proposed.
