Effect of P content on microstructure and wear properties of ZCuPb20Sn5 alloy

The properties and friction behavior of ZCuPb 20 Sn 5 modified with P were investigated. With the P addition and content increase, the second phase appeared and gradually increased in amount. Also, the microstructure of ZCuPb 20 Sn 5 was refined and evenly distributed. The addition of P had a beneficial effect on the microstructure and properties of ZCuPb 20 Sn 5 . As the P content increased, the hardness and tensile strength of ZCuPb 20 Sn 5 increased, but the elongation, the friction coefficient and the wear rate decreased. The wear mechanism of ZCuPb 20 Sn 5 was mainly adhesive wear, and a small amount of debris was produced. As the P content increased, the anti-wear resistance of ZCuPb 20 Sn 5 deteriorated. The properties and friction behavior of ZCuPb 20 Sn 5 modified with P were investigated.
