先進的电拋光之所以难於推廣,是由於对抛光時所採用的电解質的要求,大多數是稀有或貴重的、而常常又是有碍健康的化学藥品,如鉻酐、檸檬酸、氫氟酸等。除此以外,还需要对电解質加熱和襯鉛槽。我們提出用草酸或它的鹽所組成的草酸电解質來抛光鋼和有色金属。可以推測,有很大的趨势构成强的複合物。草酸和它的鹽会有力地降低从陽極表面凹处的腐蝕和擴散过程的速度(利用含金属多的可溶解複合物時,凹处的鈍化作用很坏),为凸处的腐蝕和擴散創造了良好的条件,因而主要是溶解了凸处。实际試驗指出:为了形成複合物和得到所要求的表面光潔度,少量的草酸就够了。抛光过程的進
The reason why advanced electropolishing is difficult to promote is due to the electrolyte requirements for polishing, most of which are rare or expensive and often unhealthy chemicals such as chromic anhydride, citric acid, hydrogen Fluoric acid and so on. In addition to this, there is a need for electrolyte heating and lined lead baths. We propose to polish steel and non-ferrous metals with oxalic acid electrolytes consisting of oxalic acid or its salts. It can be speculated that there is a strong tendency to form strong complexes. Oxalic acid and its salts strongly reduce the rate of corrosion and diffusion from the anodic surface pockets (the deactivation of the pockets is very bad with soluble composites containing a large amount of metal) creating for the erosion and diffusion of the projections A good condition, which is mainly dissolved convex. Practical tests point out that a small amount of oxalic acid is enough to form the complex and achieve the desired surface finish. Progress of the polishing process
