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-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 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]
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 ]
OPEC+ faces a major oil oversupply in 2025, challenging production increases. The coalition has tried to boost oil prices by holding back output. Instead, members are ceding control to non-OPEC ...
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.
