Nickel plating is commonly used on brass plumbing fixtures to make them look bright and silvery. Vinegar. During the procedure, the parts to be electroplated are often hung from conveyors. In this article, we’ll discuss exactly that, as well as the many stages that must be done in order to get the best result possible. Why electroplating is done? Electrolysis is widely used for electroplating. There are different types of electroplating likeChromium PlatingGold and Silver PlatingTin PlatingZinc PlatingLet’s look at them one by oneChromium PlatingIt is done on different objects like car parts, bath taps, kitchen burners, bicycle handlesIn this case, layer of chromium metal is deposited ove Why is Electroplating Done It is done because Metal has some property which the other Metal lacks Uses of Electroplating Some uses of electroplating are To prevent from Corrosion : We usually do tin coating to steel cans to prevent corrosion The object to be plated and the metal are dipped into the aqueous solution containing the metal ions. Chrome is always applied by electroplating, it is never melted onto parts in the fashion of chocolate on strawberries, sprayed on like paint, or applied in any other way than by electroplating. Otherwise, the plating cannot be done evenly. Listed below are some of the industries SPC serves and how they apply electroplating: Automotive industry: Plating is commonly used in the automotive industry to prevent corrosion in harsh environmental conditions. Both types use the same electrolyte to immerse both electrodes. That's why electroplating is widely used across a variety of industries. Electroplating is used in jewelry making to coat base metals with precious metals to make them more attractive and valuable and sometimes more durable. Metals such as gold and silver are plated for decoration: it's cheaper to have gold- or silver-plated jewelry than solid items made from these heavy, expensive, precious substances. 1)Protection from corrosion. The electrodes used in electroplating are non-inert - they do take part in the electrolysis reactions. Pros: electroplating can protect more vulnerable metals from corrosion.
