  Abstract


The aim of this work is to study the effects of corrosion behavior on diffusion bonded AA5083, AA6082 and AA7075 aluminum alloy. The microbiologically influenced corrosion (MIC) behaviour of aluminium alloys is estimated in natural aqueous environment. An optical microscopy is used to confirm the micro colony formation of rod and cocci bacterial species. Polarization study is also carried out to determine the shift in free corrosion potential of metallic structure due to biofilm formation. Corrosion rate is determined by finding the intersection point of Ecorr and Icorr in the polarization curve.AA7075 found to corrode higher than the corresponding welded region of joints. Similarly the corrosion current and corrosion rates are higher for the AA7075 compared to the AA6082 and AA5083. The corrosion rates observed were 2.47, 9.93 and 12.14 mm/year for AA6082, AA5083 and AA7075 respectively at diffusion bonded zones.
