【摘要】 本文介绍HCr-2镀铬催化剂,它不但保留了HCr-1的全部可贵特性,还较大的加宽了镀层光亮区的电流密度范围,镀层清亮光滑、不易生瘤,还使阴极电流效率又提高约5～6％,即η_k高达50～55％。更多还原

【Abstract】 This paper introduces H Cr-2 as a catalyst for hard chromium Plating.Besides-the maintenance of the characteristics of HCr-1. HCr-2 considerably brodens theange of current densities for obtaining bright coating with the deposit havingrmooth surface and less trend of nodule, and further increases the cathodic curr-sent efficiency (ηk) by 5-6%, i, e.ηk can reach 50-55%.更多还原
