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。 The occurrence and development of pitting corrosion is not only restricted by material factors, but also influenced by environmental conditions. Since the total surface area of ​​the pores in the growth process has been changing, it is very difficult to directly measure the growth rate of the pores. Therefore, artificial orifice model was used to study the growth of pores. In this work, the influence of environmental factors on the anodic dissolution of carbon steel single hole and the composition and function of the film on the surface of the etching hole were studied by using artificial hole model system.
