Sodium hypophosphite is mainly used for electroless nickel plating.

Electroless nickel plating has several advantages versus electroplating.

Electroless nickel plating is non-magnetic and amorphous.

Electroless nickel plating contains phosphorus.

More clearly stated, successful electroless nickel plating requires both strict adherence to bath operating guidelines and optimal surface preparation.

The most common form of electroless nickel plating produces a nickel phosphorus alloy coating.

Electroless nickel plating is an auto-catalytic reaction used to deposit a coating of nickel on a substrate.

Before performing electroless nickel plating, the material to be plated must be cleaned by a series of chemicals, this is known as the pre-treatment process.

It consists of an electroless nickel plating covered with a thin layer of immersion gold, which protects the nickel from oxidation.

Hypophosphites are used in electroless nickel plating as the reducing agent to deposit for example Ni metal from Ni salts.

Usually the beryllium mirror is coated with hard electroless nickel plating which can be more easily polished to a finer optical finish than beryllium.

It is also used to reduce metal salts and oxides to the pure metals in electroless nickel plating and plutonium extraction from nuclear reactor waste.

Electroless nickel plating is self-catalyzing process, the resultant nickel layer is NiP compound, with 7-11% phosphorus content.

Electroless nickel plating uses hypophosphite as the reducer while plating of other metals like silver, gold and copper typically use low molecular weight aldehydes.

In industry it can refer to the alkaline solutions used in a dipping (immersion) process to plate aluminium with zinc prior to electrolytic or electroless nickel plating.

The template was then coated with a thin layer of metal by electroless nickel plating, and the template is etched away, leaving a free-standing, periodic porous metallic structure.

Electroless nickel plating (EN) is an auto-catalytic chemical technique used to deposit a layer of nickel-phosphorus or nickel-boron alloy on a solid workpiece, such as metal or plastic.

The most common electroless plating method is electroless nickel plating, although silver, gold and copper layers can also be applied in this manner, as in the technique of Angel gilding.

They added new machines for electroless nickel plating and bronzing (and made the floors slip-proof with expanded mesh, stainless-steel fencing panels supplied from the nearby fallen "Iron Curtain!")

Electroless nickel plating, also known as enickel and NiP, offers many advantages: uniform layer thickness over most complicated surfaces, direct plating of ferrous metals (steel), superior wear and corrosion resistance to electroplated nickel or chrome.

Much of the chrome plating done in aerospace industry can be replaced with electroless nickel plating, again environmental costs, costs of hexavalent chromium waste disposal and notorious tendency of uneven current distribution favor electroless nickel plating.
