The Ti6Al4V alloy is one of the key materials for implementation in biological applications, such as medical implants. Due to its poor wear resistance, significant research investment is directed towards this field. In this work, we determined the tribological properties of the Ti6Al4V alloy by measuring the coefficient of friction and wear factor, while varying the test parameters. Tribological tests were performed using a reciprocating sliding tribometer with a contact configuration of Ti6Al4V alloy plate and ZrO2 ball, lubricated with a phosphate-buffered saline (PBS) solution at 37°C. The measured coefficient of friction was weakly dependent on the normal load and slightly decreased with its increase. Wear increased with the rise in sliding speed and normal load. The results of the wear track characterization on the Ti6Al4V alloy indicate that the primary wear mechanism between the contact surfaces is abrasion, whereas the ZrO2 ball exhibited minor adhesion.
