Friction Resistant Composite Materials

With the development of cars, tractors, railway vehicles, and with growing requirements on speed, performance and reliability, the demands on development of high temperature resistant friction materials are increasing, which could satisfy the high safety requirements and environment protection. This contribution concerns the development of new metal-ceramic friction materials. Metal-ceramic friction composites are multi–component materials, beside basic metal matrix (bronze) they contain slide additives (graphite) and friction additives (SiO2-SiC). Many applications of such alloy P/M parts are based on these characteristics such as controlled porosity and friction applications(brakes and clutches)applied in automotive industry. The most problems which cause road accidents occur because of brake systems. For this reason metallic brakes are important automotive parts. The advantages of metallic brakes are absorbing more energy under high speed, more wear resistance, high heat conductivity which helps in heat dissipation and stable friction coefficient. This book, therefore, explains the corrosive wear of bronze friction resistant composites prepared by powder metallurgy technique.
