At Cadorath, COPPER PLATING is applied in an electrolytic cell through the process of electrolysis, employing direct current that dissolves copper rods in order for the metal’s ions to attach to the substrate. The water itself contains an ionic solution which allows for the transfer. Electrical current causes the copper to become oxidized, forming a thin, solid, metallic copper film on the surface of the item.
ADVANTAGES OF COPPER PLATING
- Often used as an activation process for another coating, such as tin, chrome, nickel or silver.
- As a soft metal, copper is extremely malleable and excellent for maintaining adhesion.
- Copper provides smooth and even coverage when applied.
- Provides anti-bacterial properties and widely used in medical instrument applications.
ORIGINS AND DEVELOPMENT
The application of copper plating is identical to battery technology, with copper rods acting as the anode and the substrate material receiving the coating as the cathode.
Through the application of copper, various other chemicals are often added to improve plating uniformity and brightness. These additives can be anything from dish soap to proprietary compounds. Without some form of additive, it’s almost impossible to obtain a smooth plated surface.
