Web7 Nov 2016 · This paper aims to construct the E-pH diagrams for AISI 316L stainless steel in chloride solutions containing SO42− ions and therefore investigate the role of SO42− ions on pitting corrosion of stainless steel.,A cyclic potentiodynamic polarisation method was performed to obtain polarisation curves at different pH. From these curves, corrosion, …
