Abstract
We study the effect of sulfate reducing bacteria on the electrochemical conditions at the tips of stationary and growing corrosion fatigue cracks in 40Kh steel specimens in Postgate medium. Sulfate-reducing bacteria change significantly the pH and the electrochemical potential at the crack tip and greatly decrease the efficiency of KXO inhibitor. The effect of sulfate-reducing bacteria and KXO inhibitor on the intensity of local anodic dissolution and hydrogen embrittlement in the vicinity of a corrosion fatigue crack tip is estimated.
