Study on tribology of liquid-solid formed CuPb20Sn5/Carbon steel bimetal
Taking CuPb _20 Sn _5 as the research object, the CuPb _20 Sn _5 /Carbon steel bimetallic sample was prepared by the solid-liquid compound method, and the relationship between the microstructure and friction properties of the bimetallic CuPb _20 Sn _5 layer. The results show that the Cu _3 P and δ (...

| description | Taking CuPb _20 Sn _5 as the research object, the CuPb _20 Sn _5 /Carbon steel bimetallic sample was prepared by the solid-liquid compound method, and the relationship between the microstructure and friction properties of the bimetallic CuPb _20 Sn _5 layer. The results show that the Cu _3 P and δ (Cu _31 Sn _8 ) phases in CuPb _20 Sn _5 are distributed in the α -Cu to improve the wear resistance of the alloy. The friction coefficient fluctuates in the range of 0.057 ∼ 0.093, when the load was 150 N-350 N. When the speed exceeds 3.86 m s ^−1 , as the load increases, the friction coefficient first increases and then decreases, and the wear rate increases. When the load was less than 250 N, the wear surface of CuPb _20 Sn _5 was smooth, and the material was basically free of wear. When the load was 300 N, the friction coefficient reaches the lowest point, and the third body friction layer was formed in CuPb _20 Sn _5 layer, and the wear mechanism was slight adhesive wear. When the load was greater than 300 N, Pb will fall off the CuPb _20 Sn _5 surface, and the friction coefficient increase, causing abrasive wear. |
