Sherardizing

Sherardizing is the process of choice for components that require long-term corrosion resistance.

Sherardizing is available in a range of coating thicknesses from 15-80µm, that prevent rust by creating a uniform zinc alloy coating that is both damage resistant and cost effective.    

Sheradizing is a diffusion process in which components are heated in the presence of zinc dust, at a temperatures ranging from 320-500ºC.  The resultant Zinc/Iron alloy coating is subsequently Zinc Phosphated, resulting in a clean, passivated, matt grey surface 

Main Benefits

• Long Term Corrosion protection

• Coating thickness range available 15-80 microns

• Salt spray resistance sherardizing - 96 hours sherardizing 2000 - 500 hours

• Damage Resistant

• Uniform Coating

Properties

• Long Term sacrifical environmental protection

• Uniform diffused zinc/iron alloy coating

• Protection of irregularly shaped and recessed components

• Relatively high degree of wear and abrasion resistance.

• No hydrogen enbrittlement

• Matt grey textured surface, suitable for the application of paint systems

• Relatively low processing temperature

• Dry process suitable for sintered material.

Applications

• Rubber bonding - anti roll bar link

• Mining Industry - roof support hinge pins

• Submarine telecommunications systems - bend limiters, universal joints

• Rail track fittings
