摘要: 

对硝酸级(NAG)310L不锈钢焊接接头在含氧化性离子的沸腾硝酸中进行浸泡实验及金相分析。研究表明,在不同Cr6+含量的沸腾 40%HNO3中,材料的腐蚀程度主要受Cr6+含量的影响。随Cr6+含量的增加,母材和焊缝均出现不同程度腐蚀,但焊缝较母材腐蚀严重。 Cr6+含量是促进焊缝过钝化腐蚀和晶间腐蚀的主要因素。

关键词 HNO3Cr6+硝酸级310L不锈钢过钝化腐蚀晶间腐蚀    
Abstract

orrosion resistance of welding joints of 310L(NAG) stainless steel in boiling nitric acid with different Cr6+ ions contents was investigated. It is shown that Cr6+ ions can remarkably enhance corrosion attack on welding joints, and with intergranular attack in heat affected zone and weld metal. The weld metal was suffered more severely corrosion attack, but in pure boiling nitric acid, welding joints exhibit strong corrosion resistance.

Key wordsnitric acid, Cr6+ ions    310L(NAG) stainless steel    transpassive corrosion    intergranular attack
