Electroless nickel (EN) plating is an auto-catalytic reaction that deposits an even layer of nickel-phosphorus or nickel-boron alloy on the surface of a solid material, or substrate, like metal or plastic.The process involves dipping the substrate in a bath of plating solution, where a reducing agent, like hydrated sodium hypophosphite (NaPO 2 H 2 · H 2 O), reacts with the material's ions to ....

Electroless Nickel plating (EN) is a process that uses a chemical reaction to co-deposit it’s Nickel-Phosphorus coating onto a desired substrate. Comparatively, this solution differs from other electroplating processes because it does not require an electricity source to coat the part.

Since electroless nickel plating relies on a chemical reduction reaction, control of the process is critical in obtaining optimum results. A typical EN bath is more sensitive to operating conditions than an electroplating bath, and care must be taken to control the process within relatively tight parameters to achieve the best performance.

Electroless Nickel Plating. Electroless nickel plating is a process that uses auto-catalytic chemical reactions to create a layer of nickel alloy to coat a metal or plastic object. The process works in such a way that the nickel alloy coating deposits directly onto the substrate as the chemical reaction creates it. Read More…

Electroless Nickel Plating is the deposition of a nickel-phophorous alloy onto a metal substrate without the use of an electrical current. The electroless nickel plating process utilizes an autocatalytic chemical reaction to deposit a reliable, repeatable coating of uniform thickness. This uniformity of deposit can, in some cases, eliminate the ...

Formula for electroless nickel plating solution. adv. A discussion started in 2002 but continuing through 2019. 2002. Q. I'd like to find out the exact recipe (components) for electroless nickel plating bath on steel (common, no special alloys). The layer has to ensure protection against corrosion. A layer about 8 to 10 microns is enough.

Of Electroless Nickel Plating Glenn 0. Mallory The chemical deposition of a metal from an aqueous solution of a salt of said metal has an electrochemical mechanism, both oxidation and reduction (redox), reactions involving the transfer of electrons between reacting chemical species.

Electroless Nickel (EN) plating is unique in that it does not require electrical charges which can result in inconsistent deposits. Instead, the EN process relies on the presence of chemical reduction agents that react with the metal ions to deposit a thin, uniform nickel coating on solid workpiece.

electroless plating will not be achieved on complex parts by electroplating. As electroless nickel plating is a chemical process with no current flow involved, the rate of nickel deposition on all areas should be equal, provided uniform solution conditions are maintained. Temperature, pH, agitation and solution composition are

Electroless plating, also known as autocatalytic plating, or conversion coating, is a way of plating your part without using an external power source. The process involves placing the part in an aqueous solution and depositing nickel, creating a catalytic reduction of nickel ions to plate the part without any electrical energy dispersal.
