Abstract The behavior of copper electro-polishing in ortho-phosphoric acid using the galvanostatic polarization method was ascertained. This was examined via measuring and comparing anode potential –limiting current relationship in solution of regularly mounting concentrations (from 50 to 1800 ppm of methanolic Allium sativum (garlic extract), Tilia cordata (Tilia leafs), Foeniculum vulgare (fennel seeds), and Lablab purpureus (Dolichos lablab extract) and weight loss method. Influence of temperature on the dissolution kinetics were investigated. First order kinetic is applicable to the copper dissolution in solution containing plant extracts. Surface morphologies, brightness and roughness of polished specimens were examined with a scanning electron microscope (SEM), reflectance and atomic force microscope (AFM). Addition of methanolic plant extract to electro-polishing solution produce a lesser limiting current. According to SEM, UV–VIS-NIR spectra and surface roughness measurements, addition of high concentration (1800 ppm) of methanolic plant extract to the electrolytic solution is highly effective to enhance surface quality. High reflection property is obtained when the different type of methanolic plant extract is added to the electro-polishing electrolyte. The minimum Ra and PV values are achieved by garlic extract, which records the highest reflectance value and inhibition efficiency. Weight loss data obtained is excellent conformity with the result obtained by electrochemical measurements.

甲醇植物提取物对正磷铜电解抛光的影响

摘要 用恒电流极化法确定了铜在正磷酸中电解抛光的行为。这是通过测量和比较阳极电位 - 定期安装浓度（从 50 到 1800 ppm 的甲醇大蒜（大蒜提取物）、Tilia cordata（Tilia 叶）、Foeniculum vulgare（茴香籽）和 Lablab）中的阳极电位-限制电流关系来检查的purpureus（Dolichos lablab 提取物）和失重法。研究了温度对溶解动力学的影响。一级动力学适用于含有植物提取物的溶液中的铜溶解。通过扫描检查抛光样品的表面形态、亮度和粗糙度电子显微镜 (SEM)、反射率和原子力显微镜 (AFM)。将甲醇植物提取物添加到电抛光溶液中会产生较小的限制电流。根据 SEM、UV-VIS-NIR 光谱和表面粗糙度测量结果，向电解溶液中添加高浓度 (1800 ppm) 的甲醇植物提取物对提高表面质量非常有效。在电解抛光液中加入不同类型的甲醇植物提取物时，可获得高反射性能。大蒜提取物达到了最低的 Ra 和 PV 值，记录了最高的反射率值和抑制效率。获得的失重数据与电化学测量获得的结果非常吻合。向电解溶液中添加高浓度 (1800 ppm) 的甲醇植物提取物对提高表面质量非常有效。在电解抛光液中加入不同类型的甲醇植物提取物时，可获得高反射性能。大蒜提取物达到了最低的 Ra 和 PV 值，记录了最高的反射率值和抑制效率。获得的失重数据与电化学测量获得的结果非常吻合。向电解溶液中添加高浓度 (1800 ppm) 的甲醇植物提取物对提高表面质量非常有效。在电解抛光液中加入不同类型的甲醇植物提取物时，可获得高反射性能。大蒜提取物达到了最低的 Ra 和 PV 值，记录了最高的反射率值和抑制效率。获得的失重数据与电化学测量获得的结果非常吻合。它记录了最高的反射值和抑制效率。获得的失重数据与电化学测量获得的结果非常吻合。它记录了最高的反射值和抑制效率。获得的失重数据与电化学测量获得的结果非常吻合。
