摘　　要：采用大气腐蚀监测(ACM)技术结合传统的失重法研究了A3钢在中性盐雾加速腐蚀试验和凝露状态下SO2气体加速腐蚀试验下的腐蚀行为及规律,并探讨了两种方法的相关性。结果表明:ACM技术与失重法间的相关性良好,ACM技术在某种程度上可替代失重法作为研究A3钢室内加速腐蚀行为及规律的有效、方便、快捷的手段。Atmospheric corrosion monitoring(ACM)technique and traditional gravimetric technique were applied to investigate the atmospheric corrosion behavior of A3 steel in neutral salt-spray test and condensed SO2 gaseous corrosion testing.The correlation between the two methods was discussed.It was found that there exists good correlation between the ACM technique and traditional gravimetric technique.And in some sense the ACM method could be used as a replacement of traditional gravimetric method to readily and conveniently study the corrosion behavior of A3 steel subjected to accelerated indoor corrosion tests.
