Effect of Surface Treatment on Corrosion Resistance of 304 Stainless Steel Implants in Tyrode Solution

Abstract: The effect of different surface preparation methods such as mechanical, chemical and electrochemical surface preparation on the formation, stability and deterioration of surface films formed on austenitic 304 stainless steel was investigated in Tyrode's physiological solution by cyclic polarization curves, AC impedance measurements surface techniques. A hysteresis loop in a cyclic polarization curve was obtained that indicates a delay in repassivation of an existing pit when the potential is scanned cathodical… Show more

“…For E >E pit , the current corresponds largely to the pitting corrosion of stainless steel. The increase in pitting susceptibility with increase in potential could be explained on the basis that an increase in the applied potential may increase the electric field across the passive film and therefore enhances the adsorption of the aggressive Br -anions on the passive electrode surface [14]. In the course of a reverse potential sweep, the current decays slowly and remains higher than the current in the anodic sweep and a loop characteristic of pitting corrosion phenomena appears.…”

“…Previous studies have shown that the electrochemical methods and slow strain rate tensile (SSRT) tests are the effective ways to study the corrosion resistance with or without applied stress [4,5,13,14]. In this study, polarization curve of X80 pipeline steel in high-pH solution was tested, from which the corrosion potential and the stable passivity region can be determined.…”
