脱锌

To overcome the problem special copper alloys, which contain an inhibitor and undergo heat treatment, have been developed which are resistant to corrosion by dezincification.

为了解决这个问题，特殊的铜合金包含防蚀剂，并经过热处理，已经可以抵抗脱锌的服饰。

An in serveice valve suffering from Dezincification has a white powdery substance of mineral stains on its exterior surface.

应用中的阀门如果出现脱锌现象，在产品表面就会出现粉状物质或矿物污点。

The paper presents some results obtained from a research about effects of rare-earthand boronrefining on the microstructure and dezincification corrosion properties of casting lead brass.

研究了加入稀土和硼细化处理对铸造铅黄铜组织和脱锌腐蚀性能的影响。

The strain rate at the crack tip for the maximum dezincification coefficient was approximately 4 times as high as initially applied strain rate.

在稳态扩展阶段，裂纹尖端导致最大脱锌系数的应变速率估计约为初始应变速率的4倍左右。

Dezincification of duplex brass , which is a form of corrosion. may occur when in contact with cart ain aggressive waters.

两相黄铜脱锌现象，是一种腐蚀，当接触到某些侵蚀性水时可能发生。

As a standard NIBCO bronze/brass balancing valves are made to be "Dezincification Resistant," which is a seal of quality and longevity.

作为标准，美国尼伯科青铜/黄铜平衡阀由"抗脱锌"材料制造，是一种优质和耐用的密封材料。

Generally, areas of high stress, such as valve stems and gate valve bodies, are primary targets of attack.

一般来说，在应力较高的区域，例如阀门阀杆和闸阀阀体，是受到脱锌现象危害的主要地方。

At an electrode potential of +0.87 V, the electrode surface was rich of acicular Sn and stannum oxide. This film would prevent the electrode from dezincification, and the current density decreased and homeostasis was reached at the same time. The corrosion mechanism of brass welded line in artificial seawater was dissolution/redeposition.

随后，电极表面积累的锡和锡的氧化物及腐蚀产物层对脱锌腐蚀有一定的阻碍作用，电流密度有所下降，最后腐蚀达到一种动态平衡，腐蚀机制为溶解－再沉积机理。

By means of electrochemical and trace amount analysis techniques the dezincification behavior of α+β biphase brass in a deaerated acidified solution of sodium chloride under condition of continuous introduction of Cu~+ into solution was studied.

本文采用电化学和痕量分析方法，研究了在连续引进铜离子的去氧酸性氯化钠溶液中α+β两相黄铜的脱锌行为。

In the process of corrosion in 3.5% NaCl solution, the ceric aluminum brass forms a homogeneous and tight corrosion film on the surface, which can inhibit the diffusion of Zn from the surface of matrix to the solution, and restrain the dezincification to a certain degree.

在NaCl (3.5%)溶液中腐蚀过程中，铈铝黄铜表面形成一层较均匀致密腐蚀产物膜，较好地阻止了Zn从基体表面向介质中扩散，在一定程度上抑制了脱锌；铈铝黄铜耐腐蚀性能略优于砷铝黄铜，腐蚀速率为6.2×10^(-3) mm/a。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
