Hexavalent chromium coating technology is one of the most sought out electrolytic coating processes adopted in the automotive industry. These coatings possess exceptional corrosion resistance, wear and tear resistance and hardness making them suitable for applications in the automotive industry. However, there has been a growing concern regarding its applications as it accounts for carcinogenic and hazardous properties. Due to this, strict restrictions have been imposed by REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) and EPA (Environmental Protection Agency) in Europe and the USA respectively regarding the usage of hexavalent chromium. As a result, there have been efforts to explore high quality coating techniques that do not depend on electrolysis.
