Electroless nickel-phosphorus plating - Wikipedia

Compared to the electrolytic process, a major advantage of electroless nickel plating is that it creates an even coating of a desired thickness and volume, even in parts with complex shape, recesses, and blind holes. Because of this property, it may often be the only option. Another major advantage of EN plating is that it does not require electrical power, electrical apparatuses, or sophisticated jigs and racks.
