过去人们一直用微量元素砷来抑制黄铜的脱锌腐蚀,并对其作用机制进行了大量研究近年来发现微量硼也能有效地抑制黄铜脱锌.经过实验,我们发现不仅单独加硼或加砷能抑制黄铜脱锌,而且硼与砷的联合加入能更有效地抑制黄铜脱锌,并且在最佳硼砷含量下黄铜基本不发生脱锌腐蚀. 这就意味着,硼、砷在抑制黄铜脱锌过程中存在着某种协同作用,正是由于这种协同作用才完全阻止了黄铜的脱锌腐蚀.本文从最佳硼、砷含量、双空位的来源、脱锌的渗流机制及晶体学模型等方面讨论黄铜的脱锌过程,以及硼、砷在抑制脱锌过程中的协同作用机制
In the past people have been using trace elements arsenic to inhibit the dezincification of brass, and its mechanism of action has been a large number of studies in recent years found that boron can effectively inhibit the dezincification of brass.After the experiment, we found that not only boron alone or Adding arsenic can inhibit the dezincification of brass, and the combination of boron and arsenic can inhibit the dezincification of brass more effectively, and the dezincification of brass does not occur at the best content of boron and arsenic.This means that boron, Arsenic in the inhibition of brass dezincification process there is a synergistic effect, it is because of this synergic effect completely prevent the dezincification of brass corrosion.In this paper, the best boron, arsenic content, double vacancy source, dezincification The seepage mechanism and the crystallographic model of the brass dezincification process, as well as boron and arsenic synergies in the inhibition of dezincification mechanism
