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 ...
ZYP Coatings also has developed boron nitride coatings that may be painted on a surface. Combustion of boron powder in nitrogen plasma at 5500 °C yields ultrafine boron nitride used for lubricants and toners. [40] Boron nitride reacts with iodine fluoride to give NI 3 in low yield. [41]
Thus, cubic boron nitride, titanium nitride, and silicon nitride are used as cutting materials and hard coatings. Hexagonal boron nitride, which adopts a layered structure, is a useful high-temperature lubricant akin to molybdenum disulfide.

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. [5] A side reaction forms elemental phosphorus (or boron) which is incorporated in the coating. The classical deposition methods follows the following steps:
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]
In Ivan Yefremov's novel Andromeda: A Space-Age Tale (written 1954–1956, published Jan 1957) boron nitride named borazon is routinely used in sublight engine parts and spaceship surface coating. In Randall Garrett's 's short story "Thin Edge" (Analog, Dec 1963) [ 5 ] a fictional borazon-tungsten cable of extraordinary tensile strength is a ...
Boriding, also called boronizing, is the process by which boron is added to a metal or alloy.It is a type of surface hardening.In this process boron atoms are diffused into the surface of a metal component.
