Effect of input process parameter on the adhesion wear characteristics of Ti-3Al-2.5V alloy: A statistical approach

Abstract

Current study focused on the effect of process variables namely normal load, sliding velocity, and sliding distance on wear characteristics of Ti-3Al-2.5V alloy. Wear study has been accomplished through pin on disc method in order to determine the specific wear rate of the titanium alloy. A central composite design (CCD) and ANOVA technique was performed to ascertain an outcome of process parameters on specific wear rate. The worn out samples were analyzed using scanning electron microscope (SEM). Study results indicated that amongst process variables, normal load is the most significant factor that influences the dry sliding wear behaviour of the alloy. however, wear rate of the alloy found to be increases with increasing the normal load and sliding velocity. Microstructure study explained the possible mechanism resulting in the behavior of the alloys.
