Characterization of the Micro-Abrasive Wear in Coatings of TaC-HfC/Au for Biomedical Implants

The object of this work was the deposition of a Ta-Hf-C thin film with a gold interlayer on stainless steel, via the physical vapor deposition (PVD) technique, in order to evaluate the properties of different systems subjected to micro-abrasive wear phenomena generated by alumina particles in Ringer...
