摘　　要：以电解低钛铝基合金、纯铝和Al-Ti中间合金等为原料,分别制备了电解加钛和熔配加钛ZL108合金,研究了不同加钛方式对ZL108合金磨损性能的影响.研究表明,加入微量的钛后,ZL108合金的耐磨性有所提高,而电解加钛ZL108合金的耐磨性优于熔配加钛ZL108合金.主要原因在于钛对组织的细化作用,而电解加钛合金的晶粒细小且分布均匀.Two kinds of ZL108 alloys containing titanium are produced with electrolytic low-titanium aluminum alloy （named as ZL108D） and pure aluminum as well as Al-Ti master alloy （named as ZL108R） respectively. The influence of different titanium alloying method on wear resistance is investigated. The results show that addition of titanium can improve the wear resistance of ZL108 alloy, while ZL108D is superior to ZL108R. It is attributed to the addition of titanium which refines the grains, while the addition with electrolytic low-titanium aluminum alloy results in better grain refinement.
