The sliding surface is formed by the deposit of the sliding surface coating on the prosthesis component. The sliding surface coating has: an antimicrobial effect and a thickness of 0.5-5 mu m； and is obtainable by a physical vapor deposition-process. An average roughness of the sliding surface is less than 0.05 mu m. An independent claim is included for a joint endoprosthesis.Buluş, bir eklem endoprotezinin bir protez bileşeni (11, 23) ile ilgilidir. Protez bileşenleri (11, 23).
