Effect of Different Titanium Alloying Method on Wear Resistance of ZL108 Alloy

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.
