The resultant zinc/iron alloyed coating is subsequently zinc phosphated or chromated, resulting in a clean, passivated, matt grey surface. The coating closely follows the contours of the base material and uniform coatings are produced on articles, including those of intricate shapes. Carbon steels, low alloy steels, sintered steels, malleable grey iron and cast iron are suitable for sherardizing. The process does not give rise to hydrogen embrittlement.
- Uniform diffused Zinc/Iron alloy coating, useful for protecting irregular shaped components i.e. Bolts, Nuts etc
- Hardest, damage resistant zinc coating available
- Matt textured grey coating
- Ideal for immediate post treatment painting if required
- Eliminates the possibility of Hydrogen Embrittlement
- Coating deposit range of 15 to 80 microns for long term corrosion protection
- Relativity low process temperature, does not affect high tensile metal properties i.e. 12.9, 10.9 and 8.8 grade bolts can be processed
- Assembly problems eliminated due to uniformity of the coating deposit
- Size Iimitation on components over 1.8m x 0.4m x 0.4m
