Explain electroplating
Verified Answer
Explain electroplating
Electroplating is known as electrodeposition because the process involves depositing a thin layer of metal onto the surface of a work piece, which is referred to as the substrate. An electric current is used to cause the desired reaction.
Here's a simplified explanation of how electroplating works: Let's suppose that a layer of gold is to be electrodeposited onto metal jewelry to improve the appearance of the piece. The plating metal, or coating, (gold) is connected to the anode (positively charged electrode) of the electrical circuit, while the jewelry piece is placed at the cathode (negatively charged electrode). Both are immersed in a specially developed electrolytic solution (bath).
At this point, a DC current is supplied to the anode, which oxidizes the metal atoms in the gold and dissolves them into the bath. The dissolved gold ions are reduced at the cathode and deposited (plated) onto the jewelry piece. Factors that impact the final plating result include:
the chemical composition and temperature of the bath
the voltage level of the electric current
the distance between the anode and the cathode
the electrical current application's length of time
