摘　　要：采用MM-W1型摩擦磨损试验机对挤压铸造ZA27合金的摩擦磨损性能进行了研究。结果表明,挤压铸造显著提高了ZA27合金的摩擦磨损性能。在转速200r/min、载荷100N、摩擦副为45钢,N32机油润滑条件下,ZA27合金的摩擦磨损性能较好,其摩擦系数为0·054,磨损率为0·0192g/s·m2。该合金不适合在干摩擦下工作。Friction and wear properties of squeeze cast ZA27 alloy were investigated with MM-W1wear tester. The results show that squeeze casting can remarkably improve the friction and wear properties of ZA27 alloy. Friction and wear properties of ZA27 alloy are better under the working parameters with rotational speed of 200 r/min, load of 100N, friction couple of 45 steel and lubricated by N32 coarse oil. Its friction coefficient is 0. 054,and wear rate is 0. 0192 g/s · m^2. Squeeze cast ZA27 alloy is not suitable to work under dry friction conditions.
