Biotribological behavior of Ag-ZrCxN1-x coatings against UHMWPE for joint prostheses devices

This study aims to evaluate the structural, mechanical and tribological properties of zirconium carbonitrides (ZrCxN1-x) coatings with embedded silver nanoparticles, produced with the intention of achieving a material with enhanced multi-functional properties, including mechanical strength, corrosio...
