| 摘 要： | 利用慢应变速率技术（SSRT），并结合电化学极化曲线和阻抗实验方法研究了苯并三氮唑（BTA）添加剂对1Cr18Ni9Ti奥氏体不锈钢在0．5mol·L－1HCl＋0．5mol·L－1NaCl溶液中应力腐蚀和均匀腐蚀的缓蚀作用．结果表明，这种添加剂的缓蚀作用主要是抑制腐蚀的阳极过程而产生的．

| Abstract: | The SCC susceptibility of 1Cr18Ni9Ti austenitic stainless steel in O.5 mol.L-1 HCl 0.5mol.L-1 NaCl solutions and the inhibiting effect of benzotriazole (BTA) for SCC and general corrosion were investigated by slow strain rate technique (SSRT), polarization measurements and electrochemical impedance spectroscopy. The results indicated that the inhibitive action of BTA can be attributed to its adsorption and inhibiting effects on the anodic reaction of metal dissolution due to the blocking of the active sites on metal surface. |
