Electroplating: Bonding metal to metal through chemistry and current

Electroplating is an electrochemical process that deposits a thin layer of metal onto a conductive surface. Used across industries from automotive to jewelry, it improves corrosion resistance, electrical conductivity, and surface aesthetics — all without altering the underlying material’s structural properties.

An electrolytic cell is assembled with four key components: the anode (the source metal), the cathode (the substrate to be plated), the electrolyte bath (a dissolved metal salt solution), and an external DC power supply. When current flows, metal ions in the solution are reduced at the cathode and deposited atom by atom onto its surface.
