Functional Single-Cell Trivalent Chromium Electroplating Method

摘要

This article will introduce and explain a completely new technology that successfully replaces hexavalent chromium compounds used in electroplating with a hazard-free, trivalent chromium-based method. More specifically, the technology relates to the hexavalent-free bath and plating method to achieve crystalline, thick, wear-resistant, functional chromium plating. Negotiations for commercialization are underway with major suppliers to the coatings industries. The functional coatings industries have recently taken an approach that suggests that only replacement alternatives to chromium metal, such as tungsten carbide, will compete with traditional hexava-lent-chromium. In fact, problems associated with electroplating with hexavalent chromium can be addressed without the necessity of using chromium "alternatives."
