Chromium plating is one of the most commonly used metal finishing processes. It provides an electroplated layer of chromium on steel, stainless steel or aluminum, which enhances the look and lifespan of the part. The chromium plating process requires an electrolyte solution, usually an alkaline solution of chromic acid, through which an electrical current is passed to attract chromium ions onto the parts surface.
Chromium plating is often used in many consumer and industrial applications because of its superior corrosion resistance and sleek, highly polished finish. In consumer applications, its often used on items such as faucets, automobile components, and plumbing supplies, while in industrial applications it finds uses in aerospace, military, medical equipment and other areas. Chromium plating also offers decreased friction and wear on the surfaces of the part, which improves its durability and enhances its performance.
There are a few different types of chromium plating that are commonly used in various applications: decorative, electroplated, and hard chromium. Decorative chromium plating is most often used for aesthetic purposes, to provide a part with a shiny, attractive finish. In this process, a thin layer of chromium is electroplated onto the part’s surface, offering protection from corrosion and enhancing the part’s appearance.
Electroplated chromium is usually a thicker deposition of chromium than decorative plating. This is a more economical solution for parts that require greater wear, or for applications where high durability and corrosion resistance are required. As electroplated chromium provides a heavier layer of protection, it helps to reduce the parts’ wear and tear, whilst still providing a superior, attractive finish.
Finally, hard chromium plating is the most durable type of chromium plating available. It uses a unique electrolytic process in which a heavy deposit of chromium is built up over time, resulting in a tougher, more resilient surface coating. While this type of chromium plating offers superior protection and performance, it is also the most costly and time consuming method of chromium plating.
Chromium plating is a relatively simple and cost-effective metal finishing process, which has been implemented in many industries for decades. It provides superior protection against corrosive elements and a stunning, polished finish. As a result, it is still widely used for both consumer and industrial applications.
