Original Abstract

This study conducts a tribological analysis of Ti6Al4V samples with and without surface structures, manufactured by 3D printing, to assess their suitability as friction pairs in joint replacements. The behaviour was analysed using a pin-on-plate tribometer under conditions simulating those typically observed in vivo, with a glass counterpart enabling optical observation. The grid structure outperformed other samples: while exhibiting comparable friction to a homogeneous surface, it was the only one capable of retaining albumin in the contact area and restoring the lubrication film after unloading. However, findings suggest further refinements are needed before the structure can be considered for application. Preliminary results indicate a need for greater proximity and regularity in structures to enhance performance.
