The running-in wear of a steel/Sic,-Al composite system
نویسندگان
چکیده
Running-in, mild and severe wear are three typical wear regimes of a wear system. The running-in wear is of particular interest in MMC/ steel systems. In this paper, the running-in wear was investigated in the system of a steel disk and Sic-particle-reinforced 2014 Al composite pins. It was found that the wear mechanisms of the system were dominated by abrasion and that the fracture of the reinforced particles played an important role. Based on the experimental observations, theoretical models were proposed for the running-in wear of both the steel and metal matrix composites, respectively. The predictions of the models were in good agreement with the experimental results.
