INVESTIGATION BIOMEDICAL CORROSION OF IMPLANT ALLOYS IN PHYSIOLOGICAL ENVIRONMENT

This study investigates the corrosion properties of biomedical implant alloys used within the human body, specifically focusing on nickel-titanium (Ni-Ti) alloys and stainless steel in various corrosive environments, including NaCl, H2SO4, and NaF. With the increasing demand for body replacement parts due to health issues and accidents, the examination of these materials is critical given their applications in devices such as hip joints, dental implants, and fracture healing aids. The research aims to evaluate microstructural changes before and after exposure to corrosive environments and assess surface roughness variations. Techniques such as X-ray diffraction (XRD) were employed to analyze titanium and stainless steel samples. The findings highlight the significant relationship between corrosion resistance and material performance in biomedical applications, ultimately contributing to the enhancement of biocompatibility and durability of implant materials. This research underscores the necessity for continued exploration into the corrosion behavior of implanted biomaterials in physiological environments to ensure long-term success in medical applications.
