SHERADISING WITH ZINC-TOUGH TECHNOLOGYTM
The sheradising process is where a component is treated with a metallurgical zinc vapour diffusion for enhanced corrosion resistance and is commonly performed in a slowly rotating container to form sherardised layers.
BENEFITS OF ZINC-TOUGH TECHNOLOGYTM
• Non-interference with metallurgical properties: The low temperature application of the coating process does not have any effect on the hardness.
• Zero risk of hydrogen embrittlement: Many coating processes such as galvanizing and electroplating bring with them the risk of embrittlement. This advanced technology poses a zero risk of hydrogen embrittlement.
• Corrosion Protection: The zinc-iron alloy coating provides corrosion protection and resistance to pitting.
• Excellent bonding surface and spark free: The zinc layer is spark free providing an excellent bonding surface ideal for further coating.
• Abrasion resistant: An abrasive resistant coating on average ≥ to 15 µ thickness.
• Environmentally friendly process: The zinc vapour thermal diffusion process is environmentally friendly (a non-toxic, heavy metal free process).
• Non-destructive testing: None-interference with non-destructive test methods such as Eddy current and magnetic particle testing.
OPTIONAL FEATURES
• Extended bolts and UNC threads on application.
