Copper Electroplating

Cu²⁺ + 2e⁻ → Cu

Обзор

Copper ions from a CuSO₄ solution are reduced at the cathode surface, depositing a thin layer of metallic copper. The anode is typically a copper bar that dissolves to replenish Cu²⁺ in solution. Current density, temperature, and additives control the deposit quality, grain size, and brightness.
