- Abstract
Biomaterials are used to make devices to replace a part or a function of the body in safe, reliably economically, and physiologically acceptable manner. Several types of materials have been developed for this purpose. The most common classes of metal materials used as biomedical materials are stainless steel, Cobalt chromium alloy, Titanium and Ti-6Al- 4V. Cobalt based alloys have been used for biomedical implants for a number of years. They are now frequently used for the metal-on-metal hip resurfacing joints due to their better corrosion resistance and wear performance. Biomaterials in the form of implants (joint replacements) are widely used to replace and/or restore the function of traumatized or degenerated tissues or organs, and thus improve the quality of life of the patients. The first and foremost requirement for the choice of the biomaterial is its acceptability by the human body. A biomaterial used for implant should possess some important properties in order to long-term usage in the body without rejection. This paper presents a comparison of cobalt based alloy to other metal based biomaterials in terms of mechanical properties and biocompatibility for hip joint replacement.
