The macrostructure, microstructure, hardness, and electrochemical corrosion behavior of welded joints were studied. Effects of temperature and Cl^-关于母材和焊接金属的腐蚀行为浓度进行了研究。结果表明，该焊接接头具有良好的形态，机械性能和耐腐蚀性。母材和焊接金属两者的耐腐蚀性随着温度的升高或Cl减小^-浓度。在具有高氯溶液^-浓度，基底金属和焊接金属是点蚀更敏感。焊接金属的耐腐蚀性比母金属的略低。SN - 1687-9325 UR - https://doi.org/10.1155/2018/7284246 DO - 10.1155 /七百二十八万四千二百四十六分之二千○一十八JF - 国际期刊腐蚀PB的 - Hindawi出版KW - ER -
