Ti6Al4V alloys are widely used in engineering applications due to their superior mechanical and chemical properties. This study evaluated the wear performance of additively manufactured (AM) and cast titanium alloys against various hard counter-bodies. The percentage change in the coefficient of friction (%∆COF) was calculated by comparing the COF values of AM and cast samples. The %∆COF values were +52.38% for boron carbide, -11.42% for silicon carbide, +32.43% for tungsten carbide, and +18.75% for titanium carbide. Overall, cast titanium alloys exhibited lower COF values than AM alloys, except when contact with silicon carbide. Additionally, the cast titanium alloy exhibited lower specific wear rate against silicon carbide, while the AM titanium alloy showed higher specific wear rate against tungsten carbide.
