Abstract

Various biomaterials are implanted in the human body. Sometimes artificial organs are also implanted in the body. For this purpose various metals and alloys such as Ni-Al-Fe intermetallic alloys, titanium alloy, NiTialloy, CoCrMo alloys, magnesium alloy, Cr- Ni stainless steel , Cr-Ni-Mo stainless steel, 316L stainless steelhave been employed. The corrosion resistance of these biomaterials in various synthetic body fluids such asRinger’s solution, Hank’s solution, simulated body fluids, artificial urine, blood, serum have been investigated. Usually the corrosion resistance of these materials are investigated by electrochemical studies such as polarization, AC impedance and cyclic voltammetry study. The nature of the filmformed on the metal surface has been analysed by surface analysis techniques such as SEM, AFMetc. Study of this review paper will be very useful and time saving to researchers who would like to investigate the corrosion resistance of biomaterials in synthetic body fluids. The research findings will be very useful to the medical field.
