CADMIUM & TIN CADMIUM PLATING
Cadmium plating, also known as cadmium electroplating, is a type of metallic coating that has distinct and useful properties. Typically used in the aerospace industry, cadmium is usually paired with steel, copper, various types of iron and powdered metals. Known as a sacrificial coating because it breaks down before the underlying material, Cadorath technicians use it to add a robust layer of protection. The tin cadmium process applies an additional layer on top of cadmium.
ADVANTAGES OF CADMIUM & TIN CADMIUM PLATING
- High resistance to salt water corrosion.
- Provides an exceptional bonding surface.
- Excellent conductor of electricity.
- Naturally resistant to mould and bacteria.
- Can be used easily to coat dissimilar materials.
- Can be applied in an ultra-thin, lightweight layer.
ORIGINS AND DEVELOPMENT
Cadmium plating was originally discovered in what was thought to be contaminated zinc compounds sold in German pharmacies. The means of extracting the element soon began, while the application of Cadmium on an industrial scale started in the 1930s and 1940s.
A steadfast and reliable coating process, little has changed over the decades since its refinement in the early 20th century.
