Electroplating is to deposite a thin metal layer on a conductive surface of workpiece. Some of benefits for plating include: increased resistance to corrosion, improved hardness, superior strength, resistance to wear, improved IR reflectivity improved ductility, improved solderability, improved paint adhesion, altered conductivity and for other purposes. Different plating chemicals incorporated into the process deliver anything from a semi-bright and fully bright cosmetic effect, matte or satin finishes. Generally speaking, chrome plating is much brighter than nickel plating.
Another choice of chrome plating, hard chrome is available for reducing friction, improving durability through abrasion tolerance and wear resistance in general. Hardness can be up to HRC65~69.
