Effect of Vanadium Additive on Wear Behaviour of Titanium Aluminide Super Alloy

The impact of the vanadium addition to the coefficient of friction (COF) and wear rate was determined by examining the wear properties of titanium alloys of Ti-4.5wt%Al(Ti4.5Al) + xV (x:2,4,6,8) made by spark plasma sintering technique. A dry sliding experimental technique was used to achieve the research objectives. Normal loads of 10N and 20N were applied during the experiments, which were carried out at a linear speed of 0.06 cm/s. The titanium alloy specimens were characterized using X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques. The findings showed that as the applied normal load increases, so does the wear rate. At sliding loads of 10N and 20N, respectively, a low coefficient of friction of 0.044 and 0.120 were reported for Ti4.5Al +2wt%V. Furthermore, Ti4.5Al +4wt%V showed minimum wear rates of 1.268 x 10-5 (mm3/N/M) and 3.912 x 10-5 (mm3/N/M) under typical loads of 10N and 20N.
