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-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 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:
Dinickel boride is a chemical compound of nickel and boron with formula Ni 2 B. [1] [2] It is one of the borides of nickel.The formula "Ni2 B" and the name "nickel boride" are often used for a nickel-boron catalyst obtained by reacting nickel salts with sodium borohydride.

The holiday season is incomplete for many people without holiday movies. This year, Netflix is streaming a wide range of Christmas classics and original movies.
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.
