Galvanising
Galvanising means the coating of metals such as iron or steel with stainless plating of a “more precious” metal via electrolysis.
The casting, which needs to be coated, is inserted into a brine solution of the coating metal as the negative cathode – this is the galvanic bath. The anode is insoluble or made of the same material as the coating metal. The electrolysis procedure and thus the coating is performed under direct current.
Galvanic procedures are:
- Chromium plating
- Zinc plating
- Copper plating
- Nickel plating
- Tin plating
- Silver-plating
- Gold plating
