Corrosion-Resistant Cemented Carbide for Sliding Component

Abstract

WC-Cr₃C₂-Ni cemented carbides with improved corrosion resistance are widely used as sliding components in industrial pumps. Firstly, this report presents research on the mechanical properties, corrosion mechanisms, seawater corrosion, and galvanic corrosion of WC-Cr₃C₂-Ni cemented carbides. Next, it discusses the sliding characteristics of cemented carbides, including the mechanism of sliding crack formation and the improvement of lubrication properties through the dispersion of spherical carbon. This report summarizes the advancements in the applicability of cemented carbides as sliding materials.
