摘　　要：用电化学方法研究了A3钢在有机酸中的腐蚀.结果表明:烷基链的碳原子个数对腐蚀有影响.还探讨了磷酸酯在乙酸中的作用.结果表明:磷酸酯在乙酸中具有加速腐蚀的作用.The corrosion behavior of A3 steel in acetic and organic acids was investigated by means of electrochemistry.The results show that the corrosion rates of A3 steel in organic acids were dependent on the number of carbon atoms of the acids.The effects of phosphate on the corrosion in acetic acid were also studied.The results show that phosphate can accelerate corrosion of A3 steel in acetic acid.

关 键 词：A3钢 有机酸 腐蚀 磷酸酯
