Evaluation of Tribological Properties and Condition of Ti6Al4V Titanium Alloy Surface
This paper evaluates the tribological properties and the state of the surface of Ti6Al4V (Grade 5) titanium alloy. Tribological analysis of samples was conducted at room and elevated temperature (150°C). The wear rate was evaluated with a ball-on-disc tribotester, in accordance with ASTM G-133 norm....
