摘要：

The paper presents the effect of the machining parameters and cooling strategies on the wear behavior of the wrought and Additive Manufactured Ti6Al4V used for biomedical applications. Wear tests were performed using a cylinder-on-plate configuration in a wet and temperature-controlled environment in order to investigate the reciprocating sliding wear behavior under human body conditions. The obtained results showed that the adoption of the cryogenic cooling during machining significantly affected the Ti6Al4V surface properties improving its wear performances, in terms of lower friction coefficient and less release of metal debris due to abrasive wear compared to dry cutting conditions, regardless the alloy as-delivered condition.
