Electro Plating

Electroless nickel-phosphorus plating is a chemical process that deposits an even layer of nickel-phosphorus 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 phosphorus-containing reducing agent, usually a hypophosphite salt.^[1] It is the most common version of electroless nickel plating (EN plating) and is often referred to by that name. A similar process uses a borohydride reducing agent, yielding a nickel-boron coating instead.
Advantages of Electro less Nickel Plating
• Excellent corrosion resistance_
• Excellent wear and abrasion resistance
• Good ductility, lubricity and electrical properties
• High hardness, especially when heat-treated
• Good solder ability
• Even and uniform thickness even down deep bores and recesses, and at corners and edges
• The coating can be applied as the final production operation and can meet stringent dimensional tolerances
• Can be used on both metallic and non-metallic substrates, provided they have been suitably pre-treated.
