Electroless nickel plating. From Wikipedia, the free encyclopedia. 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 process relies on the presence of a reducing agent, for example hydrated sodium hypophosphite (NaPO 2 H 2 · H 2 O) which reacts with the

Electroless plating | Article about electroless plating by

Electroless plating is used for coating nonmetallic parts. Decorative electroless plates are usually further coated with electrodeposited nickel and chromium. There are also applications for electroless deposits on metallic substrates, especially when irregularly shaped objects require a uniform coating. Electroless copper is used extensively

Electroplating Encyclopedia Britannica

It is then coated with electroless copper or nickel before further plating. A useful degree of adhesion is obtained (about 1 to 6 kg per cm [5 to 30 pounds per inch]) but is in no way comparable to the adhesion of metals to metals. Principal applications. Copperplating is used extensively to prevent case hardening of steel on specified parts. The entire article may be copperplated and the

Nickel chloride is used here to exemplify the process of electroplating for a number of reasons. First among those is simplicity. It is not recommended, however, that nickel be used for, say, school science demonstrations because some individuals are quite allergic to it. We further do not recommend that chloride salts be used because those are amenable to release chlorine gas. For school or

Tin-Palladium Catalysts for Electroless Plating | Johnson

Electroless deposition on metals is mainly confined to electroless nickel coatings used for functional applications. It normally proceeds without too much of a problem, at temperatures of 70 to 95°C, although a catalyst is needed on some metals. For example, when electroless nickel is plated on copper or brass, the part must be dipped in a dilute solution of palladium chloride. The palladium
