Electroless nickel-boron coating (often called NiB coating) is a metal plating process that can create a layer of a nickel-boron 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 boron-containing reducing agent , such as an ...
Electroless nickel plating uses nickel salts as the metal cation source and either hypophosphite (H 2 PO 2-) (or a borohydride-like compound) as a reducer. [6] A side reaction forms elemental phosphorus (or boron) which is incorporated in the coating. The classical deposition methods follows the following steps:
Electroless nickel-boron plating, an auto-catalytic chemical technique used to deposit a layer of nickel-boron alloy on a solid workpiece Topics referred to by the same term This disambiguation page lists articles associated with the title Nickel plating .
Electroless nickel-phosphorus coatings with less than 7% phosphorus are solid solutions with a microcrystalline structure, with each grain 2–6 nm across. Coatings with more than 10% phosphorus are amorphous. Between these two limits, the coating is a mixture of amorphous and microcrystalline materials. [16]
Electroless processes are widely used to deposit nickel-phosphorus or nickel-boron alloys for wear and corrosion resistance, silver for mirror-making, copper for printed circuit boards, and many more. A major advantage of these processes over electroplating is that they can produce coatings of uniform thickness over surfaces of arbitrary shape ...

The NFL's six wild-card games feature some potentially entertaining affairs – and maybe a few duds along the way to boot.
"Black nickel" is a dark coating that consists primarily of nickel sulfide and metallic zinc and nickel. [14] It is typically plated on brass, bronze, or steel in order to produce a non-reflective surface. [15] This type of plating is used for decorative and military purposes and does not offer much protection. [1] [2] [15]
