摘要:

采用电化学以及表面观察的方法研究了海水的溶解氧和流速对于B30铜镍合金表面成膜的影响。结果表明,材料表面膜层的保护性随着海水中溶解氧浓度的提高而提高；在流速为0~2.0 m/s范围内,随着流速的增大,形成的膜层质量呈现先变好再变差的趋势；在流速为0.8 m/s左右时,形成的膜层最为致密完整。溶解氧通过影响其成膜的反应过程影响成膜质量；流速通过改变试样周围的溶解氧浓度以及产生一个冲刷作用来影响成膜,溶解氧浓度的提高有利于膜层的形成,海水的冲刷作用则会破坏形成的膜层。

Abstract：

B30 Cu-Ni alloy was widely used in the manufacture of marine condenser because of its excellent characteristics, but there was still a serious pitting problem in the actual working conditions. Because the corrosion resistance of B30 Cu-Ni alloy was related to the protective film formed on its surface, therefore, it is worthy to clarify the influence factors for the passivation film formation of B30 Cu-Ni alloy in an artificial seawater. Hence this article aims to examine the effect of dissolved oxygen and flow rate of the seawater on the film formation by means of electrochemical measurement and surface observation methods, so that the optimal conditions for the film formation were determined. The results showed that the protective property of the surface film increased with the increase of dissolved oxygen concentration (DO) in the seawater. In the range of flow rate of 0-2.0 m/s, with the increase of flow rate, the quality of the formed film first became better and then worse. The film formed on B30 Cu-Ni alloy was the most compact and complete when the flow rate was about 0.8 m/s. Dissolved oxygen affected the quality of film formation by varying the reaction process of film formation. The flow velocity affected the film formation by changing the dissolved oxygen concentration around the sample and producing a scouring effect. The increase of dissolved oxygen concentration was conducive to the formation of the film, while the scouring effect of seawater would destroy the formed film.

Key words： B30 Cu-Ni alloy film formation flow rate dissolved oxygen
