| 摘 要： | 目的研究海洋用钢焊接接头的海水腐蚀行为。方法采用海水暴露试验、电偶腐蚀试验和腐蚀电位测量等方法。结果获得了5种海洋用钢焊接接头的海水腐蚀结果。结论海洋用钢焊接接头的熔合区易产生腐蚀沟槽。在全浸区、潮差区和飞溅区条件下,同一焊接接头的腐蚀行为相同,焊接接头的腐蚀严重程度顺序为全浸区潮差区飞溅区。焊缝-母材的电偶腐蚀试验结果与焊接接头的暴露腐蚀结果一致。

| Abstract: | Objective To investigate the seawater corrosion behavior of welding joints of steels for marine application. Methods The methods including exposure tests, galvanic corrosion tests and potential measurements were carried out for the study. Results Seawater corrosion results of welding joints of steels for marine application were obtained. Conclusion Corrosion grooves were easily occurred in the fusion zone of welding joints. Corrosion behavior of certain welding joint of the steels is same among full immersion zone, tidal zone and splash zone; the order of localized corrosion degree of is full immersion zone> tidal zone> splash zone. Results of galvanic corrosion tests of weld metal-base metal are consistent well to the exposure tests of the welding joints in seawater. |
