摘要:

在大陈岛海域围海养殖基地对新型HSn70-1铜围网进行应用研究。铜围网在各海洋腐蚀区带发生了明显不同的腐蚀行为。采用金相组织和形貌观察、成分分析、性能测试线扫描等方法，对不同腐蚀区带HSn70-1铜围网的腐蚀行为进行研究。结果表明，各海洋腐蚀区带中铜合金的腐蚀行为差异显著：潮差区发生局部腐蚀，点蚀、脱锌严重；全浸区腐蚀轻微，腐蚀产物膜对基体起到了一定的保护作用；该海域存在典型的冲蚀区，磨损腐蚀和脱成分腐蚀严重。

Abstract：

In recent years, sea cage culture is being carried out in the country, the very cage generally is enveloped with copper alloy net therefore, it is of significance to acquire the corrosion performance of the Cu-alloy net in seawater. In the article, the seawater exposure of a new type of 70-1 tin brass net was carried out for two years in the waters off Dachen Island of Zhejiang province. Then the corroded material was characterized by means of chemical analysis, macro- and micro-morphology observation, XRD, SEM with EDSetc. It was found that several distinct corrosion zones can be differentiated on the net along the vertical direction while the corrosion behavior of the net in each corrosion zone is significantly different. Cu-alloy suffered from serious local corrosion, pitting corrosion and dezincification in the tidal zone, but slight corrosion in the full immersion zone due to the presence of a corrosion product film. Besides, a typical erosion zone can be observed in that maritime environment, the Cu-alloy net suffered from serious erosion- and dealloying-corrosion.

Key words： new 70-1 tin brass net cage made of copper alloy marine corrosion zone corrosion behavior pitting dealloying corrosion product layer
