摘　　要：用原位钛合金化的电解低钛铝合金熔配了内燃机活塞用ZL108合金,对不同Ti的质量分数的ZL108合金进行了拉伸和磨损试验,用扫描电镜进行了拉伸断口和磨面形貌观察。试验结果和回归方程表明,在w(Ti)=0.11%～0.16%时,材料的拉伸强度最高,磨损失重最小。Tensile and wear testing of electrolytic low Ti ZL108 alloy with different Ti content for piston of internal combustion engine were conducted,and tensile fracture and wear morphology were observed by SEM.Experimental results and regressive equation showed that the alloy has the highest tensile strength and the lowest wear quantity with 0.11%～0.16% Ti content.
