Effect of microbiologically influence corrosion of dissimilar welded joint by pseudomonas aeruginosa

Microbiologically influenced corrosion (MIC) is a type of destructive corrosion that can be initiated, facilitated, or accelerated by the presence of bacteria. The study aims to assess the MIC behavior of dissimilar welded joint substrates exposed to the existence of the Pseudomonas aeruginosa inocu...
