Study on Friction and Wear Properties of Cu-Zn-Sn-Pb-Ni Alloy

In order to improve wear resistance of copper alloy, a Cu-Zn-Sn-Pb-Ni alloy was prepared. The friction and wear properties of Cu-Zn-Sn-Pb-Ni alloy sliding against GCr 15 steel were investigated by friction tester, and the morphologies of worn surface of the specimen were observed by scanning electro...

Description
Summary:In order to improve wear resistance of copper alloy, a Cu-Zn-Sn-Pb-Ni alloy was prepared. The friction and wear properties of Cu-Zn-Sn-Pb-Ni alloy sliding against GCr 15 steel were investigated by friction tester, and the morphologies of worn surface of the specimen were observed by scanning electron microscopy. The results show that the wear rate of Cu-Zn-Sn-Pb-Ni alloy increases with increasing load and friction speed, the friction coefficient decreases with increasing the friction speed, and first increases and then decreases with increasing load. The wear mechanisms of Cu-Zn-Sn-Pb-Ni alloy are mainly abrasive wear and adhesive wear. Pb phase in the alloy exhibited good lubrication, it is favorable to improve the wear resistance of the Cu-Zn-Sn-Pb-Ni alloy.
