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...
A material composed of a steel backing, a sintered porous bronze middle layer and a layer of reinforced PTFE, which is named JS material, was prepared. The friction, wear and limiting PV values of this material under dry friction as well as the lubrication of number 20 mechanical oil were studied using a MPV-1500 friction tester. The worn surface of JS material and the transfer film formed on the...
