The Wear characteristics of Cu-Sn alloy based composite prepared through powder metallurgy

Abstract

The application of Cu-Sn alloy in the industry have been increasing due to their characteristics. In this research work, Cu-Sn alloy based composite with varying weight percentage are prepared through powder metallurgy. The hardness of Cu-Sn alloy reinforced with 5% of SiO2 ­composite and Cu-Sn alloy with 5% SiO2 composite was determined. The microstructure of the fabricated composites are also examined to ensure the uniform dispersion of reinforcing particles. Further, abrasive wear studies on both composites are also done using pin on disc apparatus and the influence of sliding distance, sliding velocity, and load on wear loss were investigated. The worn surface is examined through Scanning Electron Microscopic (SEM)  and  XRD to characterize the mechanism of wear.
