Properties and applications of electroless nickel
nickelinstitute.orgElectroless nickel plating is a process for depositing a nickel alloy from aqueous solutions onto a substrate without the use of electric current. It differs, therefore, from electro-plating which depends on an external source of direct current to reduce nickel ions in the electrolyte to nickel metal on the substrate.

After each process step, the plastic is rinsed with water to prevent carry-over of solution from one bath to another. The electroplating of plastics follows the same cycle as that described for decorative chromium electroplating.
