Studies on corrosion and microfouling on 316-stainless steel were carried out in natural pond water. The effect of freshwater biofilm on corrosion of 316 stainless steel in natural e~zvironment has been found out by various methods like potential measurement, polarization and impedance measurements for an erposure period of 100 days. Fresh water biofilm was able to ennoble the corrosion potential of 316 stainless steel. Less corrosion current and high resistance values were observed for 316 stainless steel in presence of pond water biofilm. The broad phase angle obtained from impedance measurements indicates the presence of intact passive film on 316- stainless steel in the presence of natural biofilm.
