The present study is pertaining to the influence of biofilm on pitting corrosion of UNS 31603 stainless atel in the sea water medium. These materials are welded and aged at 450℃ for 10000 hours. The corrosion behavior of weld materials are compared with similarly aged base metal (BM). Corrosion studies were conducted using potentiodynamic studies in the presence and absence of bacteria G.rose at temperatures 40℃, 25℃ and 10℃ in sea water medium. Role of bacteria and its susceptibility to pitting were determined by its biofilm presence helps in corrosion protection to certain extent. But severe corrosion occurred when biofilm breaksdown. The microbial adhesion was tudied using Scanning Electron Microscope (SEM and Fourier transform Infra Red Spectrometre(FTIR).
