USING OF CoCr ALLOYS IN BIOMEDICAL APPLICATIONS ( REVIEW)

Abstract

Metals are used extensively in biomedical applications due to their mechanical strength, corrosion resistance, and biocompatibility. There are many types of metals and alloys used in this application ( stainless steel, Ti and Ti alloys, CoCr, dental amalgam, etc). This review focus on CoCr alloys which have excellent corrosion resistance and mechanical properties which make them the best choice for many types of surgical implants. There are many alloying elements used to improve the properties of CoCr alloy such as ( Zr, In, Ta, etc ) has been reviewed.
