Electroless nickel plating is also known as chemical or autocatalytic nickel plating. The process uses chemical nickel plating baths. The most common electroless nickel is deposited by the catalytic reduction of nickel ions with sodium hypophosphite in acid baths at pH 4.5–5.0 at a temperature of 85–95°C.

Unlike electroplated coatings, electroless nickel is an auto catalytic process where the coating is deposited onto a part’s surface by reducing nickel ions to metallic nickel with sodium hypo-phosphite. This chemical process avoids many of the problems associated with most metallic coatings and provides deposits with many unique characteristics.

· Understanding Electroless Nickel Plating. Electroless nickel plating, a process that meticulously transforms material surfaces, hinges on the controlled chemical reduction of nickel ions in an aqueous solution.

· Conclusions. The mechanical and wear properties of electroless nickel-boron coatings were investigated and linked to their structure. In the as-deposited state, the coating appears X-ray amorphous. Its hardness is then close to 900 hk 25 and increases up to 1225 hk 25 after heat treatment at 400 °C during 1 h.

· Electroless nickel-boron coatings are obtained by a variation of electroless nickel where boron is incorporated into the coating during deposition. The process for electroless nickel deposition has been used since 1946 ( Brenner and Riddel, 1956 ) and electroless nickel-boron was developed a few years later ( Warf and

Electroless nickel immersion gold. Electroless nickel immersion gold ( ENIG or ENi/IAu ), also known as immersion gold (Au), chemical Ni/Au or soft gold, is a metal plating process used in the manufacture of printed circuit boards (PCBs), to avoid oxidation and improve the solderability of copper contacts and plated through-holes.
