Effect of Ceramic Reinforcement Type on Friction Stability and Wear Resistance of Cu and Cu–Bronze Matrix Powder Metallurgy Brake Composites
The tribological performance of copper-matrix sintered brake pads for high-speed rail applications is strongly influenced by ceramic reinforcement type. However, a systematic comparison of SiC, ZrO2, and SiO2 within Cu and Cu–Bronze (Cu–Br) matrix systems remains limited. In this study, six powder metallurgy composites...
