摘要： 采用离心铸造方法制备了高铅锡青铜(ZCuPb22Sn1.5)合金，研究了载荷和摩擦速度对其摩擦磨损性能的影响及摩擦磨损机理.研究发现:在0.05m/s摩擦速度下，随着载荷的增加，高铅锡青铜合金摩擦系数减小，磨损率增加，当载荷增加到120N后，摩擦系数趋于稳定；在100N载荷下，随着摩擦速度的增加，摩擦系数逐渐减小，磨损率增加，摩擦速度增加到0.10m/s以后，摩擦系数迅速减小，到0.20m/s以后摩擦系数趋于稳定；当继续增加载荷和摩擦速度时，由于铅润滑膜的破坏而增加了磨损率.在摩擦磨损过程中容易在摩擦表面形成软质铅润滑膜从而起到耐磨作用.

Abstract: High lead tin-bronze (ZCuPb22Sn1.5) was produced by centrifugal casting method. The friction and wear properties of the materials were investigated at fixed loads and friction speed，and the wear mechanisms were also analyzed. The results showed that the wear rate increases and the friction coefficient decreases with the increasing the load， the friction coefficient decreases rapidly and then trends to be stable as the loads increases to 120N when the friction speed is below 0.05m/s. Similarly， at the loads of 100N the wear rate increases and the friction coefficient decreases with the increase of the friction speed when the friction speed increases to 0.10 m/s， the friction coefficient decrease rapidly， and then trends to be stable as the friction speed increases to 0.20m/s. Then， with the increase of the fixed loads and friction speed， the solid lubrication film is damaged， the wear of the materials is severe and the wear rate unstably increases. In the process of friction and wear the Pb solid lubrication film on the worn surface is stable， and the materials have good antifriction and lower wear.
