Influence of Loads and Sliding Speed on Friction and Wear Properties of Multi-component Copper Alloy

The influences of loads and sliding speed on friction and wear properties of multi-component copper alloy sliding against GCr15 steel were studied on a MMU-200 tester,and the worn surface morphologies were also analyzed by scanning electron microscope.The results show that,as loads and sliding speed increase,the wear mass loss of the copper alloy increases,and the friction coefficient of the copper alloy slightly increases,but less variation.The dominant wear form is plough wear,and adhesive wear aggravates under high sliding speed and heavy load.
