Product description

Sherardizing is a coating process that uses thermal 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. Zinc diffusion is well suited for many types of base steel. With sheradizing the controlled diffusion creates a microcrystalline Zn/Fe structure that serves as an excellent base for additional protective coatings and decorative surfaces. This practical roughness sets sherardizing apart from other zinc coating processes. At the same time, zinc diffusion creates a very uniform surface, even on complex geometric workpieces with cavities.
