Analyzing dry sliding wear behaviour of copper matrix composites reinforced with pre-coated SiCp particles

摘要: Abstract Metal matrix composites containing dispersion of hard ceramic particles in a ductile are increasingly used for automotive, aerospace and structural applications. There is need to generate data on wear performance Cu–SiCp composites, which directly useful as design parameter. This paper reports the modeling dry sliding behaviour (10–40%) composites. SiC were pre-coated with copper by three-step electroless deposition technique. Copper reinforced 10%, 20%, 30% 40% SiCp made powder metallurgy route.
