Electroplating - Electroplating Process
Electroplating, also known as electrodeposition, occurs when electric current is used to coat the surface of a metal material. This coating is produced by using the metal material to be coated as a cathode immersed in a metallic salt in an electrolytic cell. The metal of the salt is the metal used to form the plate on the metal material.

How electroplating works - Explain that Stuff
T here's no such thing as alchemy—magically changing common chemical elements into rare and valuable ones—but electroplating is possibly the next best thing. The idea is to use electricity to coat a relatively mundane metal, such as copper, with a thin layer of another, more precious metal, such as gold or silver. Electroplating has

Copper Electroplating: How It Works and Its Applications
The electrolysis process is quite simple. The cathode and anode (positive and negative terminal) attract the opposite charges from the electrolyte and the anode as well. In the process, a pure copper wire acts as an anode while the product or part that needs electroplating acts as the cathode.

How Gold Electroplating Is Done - Sharretts Plating Company
Electroplating is the process of coating one metal or metal object with a very thin layer of another metal, typically by applying a direct electric current. This partially dissolves the metals and creates a chemical bond between them. The coating applied by electroplating is usually around 0.0002 inches thick.

A Step-by-step Guide to the Zinc Electroplating Process
The process of cleaning an object involves two steps: alkaline bath and electrocleaning. Soaking the metal in an alkaline bath for 5 – 10 minutes, at about 150° F is usually enough to get rid of most of the soil and dirt. After this, the parts are cleaned further in an electrocleaner. An electric charge is applied to the metal either at its ...
