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 also can produce coatings that are free of built-in mechanical stress, or even have compressive stress. [16] A disadvantage is the higher cost of the chemicals, which are consumed in proportion to the mass of nickel deposited; whereas in electroplating the nickel ions are replenished by the metallic nickel anode.
Nickel electroplating is a process of depositing nickel onto a metal part. Parts to be plated must be clean and free of dirt, corrosion, and defects before plating can begin. [3] To clean and protect the part during the plating process, a combination of heat treating, cleaning, masking, pickling, and etching may be used. [1]
Electroless deposition is an important process in the electronic industry for metallization of substrates. Other metallization of substrates also include physical vapor deposition (PVD), chemical vapor deposition (CVD), and electroplating which produce thin metal films but require high temperature, vacuum, and a power source respectively.

Quench polish quench (QPQ) is a specialized type of nitrocarburizing case hardening that increases corrosion resistance. It is sometimes known by the brand name of Tufftride, Tenifer or Melonite. [1]
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.
Nikasil is short for nickel silicon carbide. Silicon carbide is a very hard ceramic (much harder than steel) that can be dissolved in nickel. The nickel silicon carbide solution can then be electroplated onto the aluminium cylinder bore. After the cylinders are plated, the Nikasil bores are diamond-honed to a plateau finish.
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.
