Thermal Solid Phase Diffusion

Sherardizing

Sherardizing is a coating process that uses solid phase diffusion to apply a zinc-iron layer to a steel surface. This is why it is often referred to as zinc thermal diffusion.

The resulting intermetallic zinc-iron phases bond atomically to the base material, ensuring excellent protection from corrosion. When this procedure is used, no hydrogen-induced corrosion or molten metal embrittlement occurs.

As a professional supplier of surface treatments, Impreglon takes advantage of this effective niche technology.

Impreglon Products for Sherardizing

  • ZDC®

    Zinc Diffusion Coat

    Active cathodic protection against corrosion

    Zinc diffusion is useful wherever extreme, active cathodic corrosion protection is required, e.g. in the construction and automotive industries, in traffic engineering, wind power or offshore technology.

  • FuC®

    FuseCoat®

    FuseCoat is used anywhere that there is a need for outstanding cathodic corrosion protection and other functional and decorative properties combined in a duplex coating, e.g. in the automotive and construction industries, traffic engineering, wind power, the oil and gas industry or offshore.
