Investigation on Corrosion Behaviour of PEEK Biomaterial

The evolution of biomaterials is not a modern area of science, having survived for around half a century .The study of bio materials is called biomaterial science. A bio materials essentially a material that is used and adapted for a medical application. In medical applications, biomaterials are rarely used as isolated materials but are more commonly integrated into devices or implants. Biomaterials should possess good properties for implants so that there should be good bonding which prevails when co-operating with the body and the blood. Hence the implants are tested for various respective properties. SS-304 has established itself as one of the best available bio implant material. With the advancement in the area of science, metallurgy and engineering, the improvement for more advanced biomaterials having better properties than SS-304 have been emerged. This Paper constitutes corrosion study of PEEK and PEEK used as Biomaterial. Corrosion control of metals is an important activity of technical, economic, environmental, and aesthetical importance. The use of biomaterial is one of the best options of protecting metals and alloys against corrosion. The toxicity of organic and inorganic corrosion inhibitors to the environment has prompted the search for safer corrosion in biomaterial, most of which are biodegradable and do not contain heavy metals or other toxic compounds. Study of corrosion abilities shows the PEEK biomaterial which as the maximum withstanding of corrosive material than any other material for implant on material.
