摘要: <正> 孔蚀的发生与发展既受材料因素的制约,又受环境条件的影响。由于小孔在生长过程中其总表面积一直在变化,直接测定小孔生长速度十分困难,因此有人采用人工小孔模型以研究小孔的生长规律。本工作采用人造小孔模型系统研究了环境因素对碳钢单蚀孔阳极溶解的影响规律及蚀孔内表面膜的组成与作用。

Abstract：The effect of some factors on anodic dissolution of carbon steel in man- made pit,the component and action of surface layer inside pit have been researched. It was found that anodic dissolution rate inside the man-made pit increa- ses with polarization potential values and concentration of chloride ions,After the pit getting proper depth,the relationship between its dissolution rate and pH value of solution is not priority,The anodic dissolution rate in the man- made pit with smaller diameter and depth are quicker than that of the pit with biger diameter and depth,but when diffuslon resistance form,its dissolution rate decreases more quickly,There is a resistance layer mainly consist of Fe and Cl in the bottom of the pit.
