Chromium plating companies1/11/2024 ![]() This was not isolated to the chrome platers because all industrial trades suffered the same ignorance regarding the negative effects of the chemicals they used. Up until the mid-1960, most hard chrome platers were unaware of the damage that chromic acid had on the environment. Our country would be crippled and our economy devastated without the properties that hexavalent hard chrome plating provides. In short, it is vital to America's industry, economy, security, defense, and even Her sovereignty. It is also widely used in weapon systems and aerospace applications. It found wide usage in industries like agriculture, aircraft, automotive, chemical, electrical, engines, fluid power, food processing, mining, optical, ordnance, paper, printing, railroad, textile, tooling, and even dies and molds. No other coating can provide these features as easily and inexpensively as hard chrome does. Among others, this includes surface hardness, lubricity, wearability, and corrosion resistance. The primary reason is the improved surface properties it provides to metallic parts and components. Hexavalent hard chrome quickly developed into a widely used industrial process. Many job shops, however, were smaller family-based companies with only 2-10 employees. By 1960 there were literally thousands of hard chrome OEMs and job shops some of the OEMs were large installations, as were a few of the job shops. The industry continued to expand through the 1940s and 1950s. The industry grew rapidly from these initial companies, and soon afterward, other hard chrome job shops were operating in most large cities across America. A patent infringement suit caused the merger of these two companies forming the Chromium Corporation of America, which later operated a third chrome plating plant in Waterbury, Connecticut.īy 1926 chrome plated became a buzzword for a hard, wear-resistant, and durable finish that also offered improved corrosion protection. Hard chrome plating was commercialized in 1924 with the establishment of the Chemical Treatment Company in New York and the Chromium Products Corporation in New Jersey. In 1924 the process was further developed by Colin Fink and Charles Eldridge at Columbia University. George Sargent improved the process in 1914 and established the standard 100:1 solution, which is still used today and known as the Sargent bath or the standard bath. patent for chromium plating was granted to Emile Placet and Joseph Bonnet of Paris, France, with U.S. The first known chromium electrodeposit was achieved in 1855 by German scientist Dr. To understand the future, one should start with an understanding of history and the technology involved.Įric Svenson Sr.The element chromium was discovered in 1797 and isolated in 1798. In the evaluation stage we determine minimum thickness points on each part and design the rack fixtures and the plating cycle to meet the minimum nickel electroplating thickness requirements.Details By Eric Svenson Sr., Master CEF, Plating Resources Plating The plating racks are engineered to maximize the productivity of each rack and distribute the electrical current and plating onto each part as uniformly as possible.Įlectroplating is driven by direct current electricity so the metal plating deposit can vary in thickness. Nickel plating has a white finish and the chrome plating which deposits chromium has a clear translucent finish which is hard and scratch resistant.Īll of our bright nickel chrome plating requires a special rack fixture to hold onto the parts during the plating process. The more reflective a part must be (usually referred to as an “A surface”), the smoother the surface finish needs to be before chrome plating. The appearance can be as reflective as a mirror. Mirror chrome is a good way to describe bright nickel chrome. We determine which layers of nickel to use by understanding the application, part specification, and corrosion requirements. High sulfur nickel layers and micro porous nickel layers are designed to improve the corrosion performance. There is a specific ratio for the thickness and a measurable difference in electrochemical potential of the semi-bright nickel layer to bright nickel layer. Why so many layers? The layers of nickel are structured to provide increased levels of corrosion protection. Depending on your application requirements, the layers of metal plating underneath the bright nickel chrome can include a copper strike, nickel strike, semi-bright nickel, high sulfur nickel, a layer of bright nickel, micro-porous nickel, and a final topcoat of chromium.
