The wear and friction characteristics of the CuSn10P1 copper alloy are influenced by various factors, including the sliding velocity and applied force. An investigation has been conducted to examine the influence of various loads and sliding velocities on the wear characteristics of the thixoextruded copper alloy. The annealed alloy exhibits a homogeneous distribution of the solid phase, and a liquid island presents in the solid phase. The major phases consist of α-Cu, Cu
41 Sn11 , and a few Cu3 P phases. The average coefficient of friction (COF) is between 0.6 and 1.0. SEM-EDS and three-dimensional topography instruments were used to analyze the surface topography and wear rate of reciprocating wear. When the sliding velocity was 5 mm/s, the wear rate increases from 0.07 mm3 /Nm to 0.226 mm3 /Nm as the load increases from 3 N to 9 N, in accordance with Archard's dry wear law. The worn surface exhibited groove, granular, and layered debris, and the predominant characteristics of the wear were abrasive wear and delamination wear. As the load increased, there was a transition from abrasive wear to delamination wear. [ABSTRACT FROM AUTHOR]- Published
