CORROSION MECHANISM OF A3 STEEL IN NAPHTHENIC ACID
环烷酸对A3钢腐蚀机理的研究

The corrosion rates of A3 steel in different concentrations of naphthenic acid were determined by weight loss method. The equations of corrosion rate of A3 steel in naphthenic acid were obtained by approaching to the experimental results. The corrosion mechanism of A3 steel in naphthenic acid on the basis of the equation was presented. The observation of the surface morphology of A3 steel corroded by naphthenic acid verified the reasonability of the presented corrosion mechanism.
