Use of Zinc plating is rapidly increasing for rust protection and decorative applications, It is primarily due to rise in cost of Nickel metals & also, increasing restrictions towards using toxic Cadmium in desired applications. It can also provide more uniform thickness, does not tend to fill up holes or obliterate threads and conserves heating energy to a very great extent. Zinc is an ideal replacement for hot dip galvanizing where high preci- sion is desired. Latest developments of Zinc alloy plating inconjugation of certain passivations provides extremely high corrosion resistance to the deposited coating which even surpass the service life of traditional Nickel Chrome deposits.
