Electroless nickel plating (ENP)

Electroless Nickel plating is the deposit of a nickel-alloy to the surface of a component by a chemical reduction process. To ensure the highest possible quality of surface finish, the LoneStar Group works with customers to advise on and provide the appropriate level of cleaning and pre-treatment services to every component or batch.

Once this stage is complete, components are then placed into the final nickel-plating solutions, where the desired deposit rate is closely monitored to achieve uniform, durable corrosion-resistant plating to specified thicknesses. Because the nickel plating is deposited chemically, the thickness of the plating always remains even, despite the variation of shape, form, feature or thread. The precision and uniformity of this chemical depositing ensures every element of the substrate is plated, even in precision-engineered slots, grooves, holes and on the inside of walls of piping, tubing, hydraulic pistons, cylinders, valves, or other critical industry components.

High phosphorus deposits of ENP (10-14%) create an amorphous surface finish, which means there are no grain or phase boundaries for corrosive or acidic elements to attack.
