Abstract

The corrosion resistance and the oxide film of stainless steel containing Mo in simulated condensed water of oil and gas environments were investigated by electrochemical tests and X-ray photoelectron spectroscopy. From the results of potentio-dynamic polarization, Mo improved the corrosion resistance of stainless steel in simulated condensed water. From the results of electrochemical impedance spectroscopy, the oxide film of stainless steel containing Mo had fewer defects than that of stainless steel without Mo. The results of X-ray photoelectron spectroscopy showed that the oxide film containing Mo was formed in the outermost layer on Mo containing stainless steels. The thickness of the oxide film formed on stainless steel containing Mo was thinner than that of the oxide film formed on stainless steel without Mo.
