The film has uniformity and can be processed into complex shapes.
Electroless nickel plating is a process that deposits a nickel-phosphorus (Ni-P) coating through chemical reduction without the use of electricity. A significant feature is the ability to uniformly control the thickness of the plating. The method involves applying the plating by utilizing a chemical reduction reaction in the plating solution without passing current. In the plating solution used for electroless nickel plating, sodium hypophosphite is employed as a reducing agent, which results in the deposited coating containing phosphorus. Therefore, electroless nickel plating possesses various characteristics that differ from those of conventional nickel plating.
