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
