Hard Chrome plating is a low temperature method of electro depositing chromium onto various substrate materials (steel copper brass & stainless steel )for a variety of applications. Hard Chroming increase the expected service life of components due to its high wear, corrosion and abrasion resistance.
Hard Chrome is often used to reclaim worn out or new mis-machined components that would otherwise be thrown away. Hard Chrome is also used to enhance the properties of new components. New components generally require thin deposits while component reclamation can require deposit thickness up to 1mm.
Hard Chrome has its name due to it having a high hardness value (950 – 1150 Hardness Vickers), coupled with its low co-efficient of friction (approx. half that of steel) makes Hard chrome an ideal surface for seals, bushes and other materials to run against.

What is Chrome?
Hard chrome, also known as industrial chrome, engineered chrome or functional chrome, is a metal surface coating used to reduce friction, improve durability through abrasion tolerance and wear resistance. Hard chrome has a great resistance to fretting and galling minimising wear and seizure of mating parts. expand chemical inertness to include a broader set of conditions, and bulking material for worn parts to restore their original dimensions.
