The structures of the rust layers of two low alloy steels formed by localized corrosion in marine environment were investigated. Optical microscope, electron probe, EM and microelectrochemical testing show that although the low alloy steel corrodes faster than ordinary carbon steel, but when the rust layers formed are dense and enriched with alloying elements, the corrosion processes will be inhibited. These corrosion products can form sparingly soluble salts and cover the bottom of the pits, while outside the pits this phenomena will not occur and the corrosion processes turn to enlarge the radius of the pits, as can be confirmed by the difference of the microelectrochemical mv-d curves inside and outside the pits. From the types of steels investigated, Al-Cu-P steel has more typical above mentioned characteristic, and the localized corrosion behavior of the Ni-Cu-As steel is nearly the same as that of the carbon steel.

使用光学显微镜、电子探针、电子显微镜、微电化学测试等方法对两种低合金钢在海洋条件下的局部腐蚀锈层结构进行了研究。研究工作表明,低合金钢虽然具有较碳钢严重的局部腐蚀,但当该种合金钢的局部腐蚀锈层具有合金元素富集、致密等特征时,局部腐蚀将受到抑制,其原因是蚀坑内含富集合金元素的腐蚀产物成了难溶性盐,复盖了蚀坑底部基体,阻滞了腐蚀过程,降低了局部腐蚀速度。而在蚀坑外的平坦区域则没有发现合金元素的明显富集——局部腐蚀由向深度方向转而朝着扩大蚀孔直径的方向发展。这种变化的规律可由微电化学的蚀坑内外ΔmV-d曲线明显地看到所研究的钢种中,AlCuP钢具有较为典型的上述特征。NlCuAs钢的局部腐蚀行为与碳钢相近。

A study of the rust layers fomed on low-alloy steels in sea water was made by using Mossbauer spectroscopy, X-ray diffraction, infrared absorption spectroscopy and DTA. The influences of alloying elements on the morphology of rust layers, the effect of enrichment of various alloying elements in the inner rust layer on corrosion resistance, and the crystallography of Jrust layers were discussed.

本工作用穆斯堡尔谱学等方法对几种钢的海水锈层进行了分析研究。主要分析了锈层的相组成。宏观观察表明以硅铬铜镍为合金元素的C—4钢内锈层比较致密,较厚、较坚硬、连成较大的板状块。而以锰钛为主要合金元素的C—2钢的内锈层较薄、不均匀、较脆,甚至有时不能连成一块。穆斯堡尔谱学、X线、红外吸收光谱、热差分析,都说明内锈层的主要组成相是针铁石(α—FeOOH),其颗粒的线度尺寸约为3×10~2。电子探针的锈层微区域成份分析表明、铬、铜、镍各元素在内锈层中都有富集。而锰元素与此相反,不但没有富集、反而有所消失。钛的富集情况不明显。根据本文研究结果,可以得出以下初步看法:①低合金钢中的少量合金成分对锈层中的物相组成没有明显的影响;②各合金元素在内锈层中富集与否可能影响内锈层的致密度及厚度,从而影响耐蚀性;③锈层中的物相有微晶而不是非晶质的。内锈层中主要组成物粒度已小到使其表现为超顺磁状态,在液氮温度显示反铁磁性状态。
