Studies on Mechanical and Dry sliding wear of 2014Al–SiC composites produced by powder Metallurgy route
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 11
Abstract
The aim of the present study was to investigate the effect of SiC content on the Mechanical and Dry sliding wear characteristics of a 2014Al-SiC composite. The alloy and its composites were compacted at 500 MPa and sintered in nitrogen atmosphere at 590 °C. It was found that SiC reduces the compressibility of aluminum alloys. The addition of SiC reinforcement adversely affects sintered density due to poor wetting between SiC and alloy. Hardness increased up to (5 vol %) composite and then decreases for the remaining composites having a higher SiC content. Wear studies were carried out at different load and sliding speed conditions. At a low speed wear rate, alloy with 5 vol% SiC was more than the alloy itself. However, the wear rate was lower when the SiC content was increased to 10 and 15 vol %. At higher speed the wear rate decreased with the increasing SiC content.
