Needs and importance of electroplating articles in day to day life where this technique is used
Answers
HEY !!! HERE IS YOUR ANSWER :)
Electroplating is an art of protecting metal surface form corrosion and giving it pleasant appearance. A crude metal is likely to get corroded or affected in the environmental condition, which is why electroplating is used. It is application of metallic coatings on metallic or non-metallic surfaces through electrolysis. Electroplating apart from improving aesthetics of metals also brings about change in its physical, chemical and mechanical properties. It has wide range of applications starting from protection to many industrial uses.
Some metals are considered far more attractive and valuable than others, gold and silver being the oldest and most obvious examples. But gold and silver are rare and expensive. Through electroplating, a very thin layer of gold or silver can coat a less valuable metal, making a final product with all the luster and beauty of those rare metals, at a fraction of the cost. This was the first commercial application of electroplating, and has been in use since the early 1800s. Thin layers of chromium are often used on appliances and automobiles to produce a pleasant, shiny appearance.
