摘　　要：通过失重法测定了Ａ３ 钢在不同浓度的环烷酸中的腐蚀速率，提出了环烷酸Ａ３ 钢的腐蚀机理．观察了Ａ３钢表面的腐蚀形貌，Ａ３ 钢腐蚀速率随环烷酸浓度的增加而增加．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.
