The study examines how friction damage affects corrosion resistance in WC-cBN-SiCw composite, suggesting load impacts tribological behavior.
As a kind of novel binderless composite, WC-cBN-SiCw composite possesses significant potential value in special sealing components and high-pressure medium nozzles. However, under severe wear and corrosion conditions, the surface defects caused by friction will be accelerated to become a crack source in aggressive environments. Because of the intrinsic brittleness of WC cemented carbide, its strength is extremely sensitive to local surface damage. Therefore, the influence of applied load (10 N, 20 N, 40 N and 60 N) on its tribological behavior was studied. Meanwhile, the impact of corrosion resistance of WC-cBN-SiCw composite on surface damage induced by friction was further investigated.
