Electroless Plating Method

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.

Electroless nickel

Electroless nickel-phosphorus plating is a chemical process that deposits an even layer of nickel-phosphorus alloy on the surface of a solid substrate, like metal or plastic.The process involves dipping the substrate in a water solution containing nickel salt and a phosphorus-containing reducing agent, usually a hypophosphite salt. [1]

Applications of Electroless Nickel Plating

2021/5/4Electro nickel plating is a process that uses an electrical current to coat a conductive material, typically made of metal, with a thin layer of nickel. Other metals used for electroplating include stainless steel, copper, zinc, and platinum.

Electroless plating of copper and nickel via a Sn

Abstract: Electroless plating of copper and nickel via a one-step, Sn-free activation process was carried out effectively on the SiLK/spl reg/ coating on [100]-oriented silicon wafer (SiLK-Si substrate) modified by UV-induced surface graft copolymerization with several N-containing vinyl monomers, including 1-vinylilidazole (VIDz), 2-vinylpyridine (2VP), and 4-vinylpyridine (4VP).

Electroless Deposition on Graphite Powder

2005 A. Joshi, You can sensitize ceramic or graphite powders with stannous chloride and activate them with palladium chloride solution and then later on do the electroless deposition of nickel or copper using any suitable electroless plating bath - copper or nickel.

Electroless Plating of Graphite with Copper and Nickel

2019/12/7Furthermore, the copper plating is permeable to liquids and consequently the graphite does not become completely isolated from the surrounding. The percentage of porosity filled or covered by nickel deposits is similar to copper, but they are not permeable to liquids, at least when the thickness is relatively high, and consequently the access of the liquids to the graphite is rather limited.
