NICKEL DIFFUSION COATING TECHNOLOGY
Nickel Diffusion Coating Technology to be used in heating elements for washing machines and liquid heating applications.
Diffusion coating is a process in which heating elements that will be subjected to high temperature conditions and highly corrosive environments are coated with a non-corrosive material. The process is done at elevated temperatures in a controlled chamber.
As a result, the sheath metal develops extreme resistance to corrosion, oxidation and erosion in its severe working conditions.
The advantages and differences of Nickel Diffusion
- Exactly same coating thickness on all the surface of tube
- High corrosion resistance
- High resistance against chemicals
- High resistance to degradation
- Hard to stick surface
- Slickness on the surface
