Abstract

Some electrochemical techniques such as dynamic scanning, EIS and coupon test in simulated solution with high chloride concentration were used to investigate the effect of tin on the corrosion resistance of low alloy steel. The results show that adding a little tin in the steel can restrain the anodic and cathodic corrosion behavior of all specimens in the solution and the corrosion rate decreased with the increase of tin content. Coupon test also confirms that adding tin will enhance the corrosion resistance of the steel in acid solution with high chloride concentration.
