Hexavalent chromium plating and trivalent chromium plating are the two commonly used methods for chrome plating. Analysis of the Base Material and Hard Chrome Plated Layer in an Unloaded State. Marek, Martin & Novák, Martin & Šramhauser, Karel & Svobodová, Jaroslava. The time needed varies depending on the required chrome plating thickness and the current application. Depending on the current, metal objects can be coated at a slow or quick rate. The plating bath is subsequently subjected to an electric current for a predetermined period. Sometimes the component is electrically live when it is placed in the chrome plating vat. Nimonic alloys are frequently etched using ferric chloride. Different etching solutions, such as hydrochloric, hydrofluoric, and sulfuric acids, are required for different substrates. Depending on the kind of substrate being plated, the pretreatment procedure has several variants. Various pretreatments, such as using a degreaser to get rid of thick soil, and manual cleaning to get rid of any surface contaminants and lingering signs of dirt are employed. This is done before placing the desired object into a chrome plating vat. In addition to being visually appealing, the chromed coating may provide corrosion resistance, ease of cleaning, or enhanced surface hardness.Ī flawless metal coating can be formed on the target object using the electroplating method, which involves reducing dissolved metal cations in an electrolyte salt bath. A metal workpiece or object is finished by having chromium applied to its surface. A chrome-plated object is referred to as chrome. What is Chrome Plating and How Does it Work?Ĭhrome plating is the technique of electroplating a very thin layer of chromium onto a metal surface. ![]() For corrosion and wear resistance, different chromium alloy coatings can be created via chrome plating with a range of deposition thicknesses. The process of electroplating a thin layer of chromium onto a metal object can be done to add aesthetic appeal or to make the surface harder and more corrosion-resistant.Ĭhrome plating can produce chromium layers as thin as 0.001 inches (0.025 mm). One of the main applications of chromium is the production of stainless steel and chrome plating.
