Abstract
The microbiologically influenced corrosion (MIC) susceptibility of friction stir welded (FSW) S32654 super austenitic stainless steel (SASS) in the presence of acid producing bacterium Acidithiobacillus caldus SM-1 was investigated by surface analysis techniques and electrochemical measurements. The average depth of pits shown on the FSW coupon surface was 2.8
