Co-Cr-Mo Alloys for Medical Endoprostheses: Review

Abstract

The article presents a literature review of Co-Cr-Mo alloys used in medicine for the manufacture of endoprostheses. The basic compositions of alloys of this type, as well as microstructure and their properties are considered. The questions of manufacturing by casting as well as methods of heat treatment of medical products are touched upon. It was found that the use of heat treatment allows to obtain the necessary microstructure, as well as to increase the strength properties. In addition, the methods of finishing of medical devices, which contribute to the improvement of tribological properties, were considered.
