Electroplating is a process that allows the deposition of metal layer on an object made of a different material.
Why using electroplating?
Electroplating allows the combination of the benefits of both the substrate material and the metal coating material. In other words, affordable and/or lightweight metals or plastics may be used as substrates, while the metal coating provides strength, electrical conductivity, wear and corrosion resistance, as well as improves the aesthetic appearance of the final product.
What are the main components of this process?
Here are some key points regarding electroplating:
How is it performed?
During the electrodeposition of the metal layer to the substrate material, controlled electrolysis is used. The anode and cathode are inserted into an electrolyte chemical bath and connected to the power supply. The electric current is then passed through the electrolyte. The positively charged metal ions in the electrolyte are attached to the negatively charged cathode, producing a thin metal plate. Oxidation occurs in the anode, releasing more metal ions to the electrolyte solution, so that the solution remains at the same levels of metal ions.
