Abstract		For optimal performance in physiological environments, implant material used for manufacture of various implants and joint replacements should have suitable properties. One of the most important is a high corrosion resistance required to avoid the degradation in a harsch chemical environment of human body. Three main classes of metallic materials are used in orthopaedics: titanium and titanium-based alloys (c.p. Ti, Ti-6AI-4V, Ti-6AI-7Nb), cobalt-based alloys (Co-28Co-6Mo, Co-36Ni-23Cr-6Mo) and stainless steel (Fe-12Ni-17Cr-2Mo). Besides corrosion resistance these materials should have suitable mechanical properties as well - high tensile strength and fracture toughness, and low Young elastic modulus and density. In dental applications cobalt-based, nickelbased and titanium-based alloys are used (Co-28Cr-6Mo, Ni-14Cr-6Mo, Ti-6A-14V). Corrosion resistance and biocompatibility of a material in biological environment are investigated using in vitro electrochemical measurements in simulated physiological solution.
