Definition - What does Cadmium Coating mean?
A cadmium coating is a silvery-white corrosion preventative layer containing the chemical element cadmium, which has the chemical symbol Cd and atomic number 48.
Cadmium coatings are used on very specific substrate metals to provide protection against corrosion. These substrates are typically iron, aluminum and steel. Cadmium provides superior protection against corrosion in alkaline and marine environments.
Corrosionpedia explains Cadmium Coating
Cadmium metallic coatings provide a range of unique protection properties, including:
- Good lubricity due to a small coefficient of friction
- Enhanced electrical conductivity
- Enhanced solderability
- Good resistance against general wear and cavitation
