Metrological Evaluation of the Tribological Behavior of Laser Surface Treated Ti6Al4 V Alloy

Nowadays, most of the studies conducted on procedures applying to the materials in order to increase the performance thereof, has been based on the improvement of the mechanical properties, favoring its manufacturability. New techniques of surface treatments by thermal processes and coatings, have managed to produce surface microstructures whose behavior under sliding conditions have allowed saving tribological and thermal limitations. This contribution aims at the metrological based evaluation of the friction wear of Ti6Al4 V titanium alloys samples to subjected to surface oxidation through laser radiation. For this purpose, several methodology processes have been designed and planned for the characterization and evaluation of the loss of material on the external layer caused by sliding wear, in order to identify the type of predominant wear mechanism and quantify its effects.
