ELECTROCHEMICAL STUDIES ON THE CORROSION BEHAVIOUR OF METALS AND ALLOYS IN SIMULATED RINGER ‘S SOLUTION

摘要

In modern History, metals and alloys have been used as implants. In the early development, metal implants faced corrosion and insufficient strength problems. Metal implants experienced vast development and clinical use. Type of metal used in biomedical depends on specific implant applications. SS316L & Ni-Cr are still the most used alloy in all implants division ranging from Cardiovascular to Otorhinology. However, when the implant requires high wear resistance such as artificial joints, SS316L and Ni-Cr alloys are better served. This work aims at studying the electrochemical behavior of meals like Ni-Cr, SS316L, and Gold22 & Gold18 and for comparative purpose mild steel in the presence of Simulated Ringer Solution. The behavior of metals was mentioned by Electrochemical Impedance Spectroscopy (EIS) .All the experiments were carried out at a constant temperature at 370 C.
