Abstract

Chemical polishing of metals using nanostructured media—reverse microemulsions has been studied using the example of aluminum. It has been shown that the surface roughness of aluminum foil reduced after the treatment with reverse microemulsion of sodium bis-(2-ethylhexyi)phosphate in kerosene containing an aqueous solution of hydrochloric acid with a concentration of 0.11 mol/L inside the drops. At a polishing time of 2 h, the average roughness was reduced from 54 to 28 nm. Compositions that do not form microemulsions (aqueous solution of hydrochloric acid, solution of tributylphosphate adduct with hydrochloric acid in kerosene, or dispersion of sodium bis-(2-ethylhexyl)phosphate in an aqueous solution of hydrochloric acid), have not exhibited such an effect. Additional exposure to ultrasound at the same process duration, the introduction of tributylphosphate into the microemulsion, and the replacement of hydrochloric acid with acetic or nitric acid had virtually no effect on the results of chemical polishing.

含酸反向微乳对铝的化学抛光

摘要

使用纳米结构的介质（反向微乳液）对金属进行化学抛光已经以铝为例进行了研究。业已表明，用双-（2-乙基己基）磷酸钠在含有0.11mol / L浓度的盐酸水溶液的煤油中的反微乳液双-（2-乙基己基）磷酸钠处理后，铝箔的表面粗糙度降低。在2小时的抛光时间，平均粗糙度从54纳米降低到28纳米。不形成微乳状液的组合物（盐酸水溶液，磷酸三丁酯加合物与盐酸在煤油中的溶液或双（2-乙基己基）磷酸钠在盐酸水溶液中的分散） 。在相同的过程持续时间内额外暴露于超声，
