Abstract
The main objective of the article is to provide a deeper understanding of the wear and wear transition of Al-6061/alumina particulate composite. Detailed experiments were performed under unlubricated conditions within a load range of 10—150 N and a sliding speed range of 1.25—10 m/s. A mild wear region and a severe wear region have been observed during the experiment. At mild wear, mechanical mixture layer (MML) are formed on the worn surface mainly in composites, which plays a vital role in reducing the wear rate and delaying the transition to severe wear. It is observed that the transition to severe wear occurs when severe plastic deformation induces the wear. The scanning electron microscope (SEM) is used to identify and classify the wear regions in wear mechanism.
