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 comion rates of A3 steel in different concentrations of naphthenic acid were determined by weight lass method. ?he ~uations of corrosion rate of A3 steel in naphthenic acid were obtained by approaching to the experimental results. ?he comion mechanism of A3 steel in naphthenic acid on the basis of the equation was presented. ?he observation of the surface mrpholcgv of A3 steel coded by naphthenic acid verified the reasonability of the presented corrosion mechanism.
