Electroless nickel plating is a chemical process used to deposit a layer of 902% nickel alloyed with 10% phosphorus (Ni-P) on a substrate. This industrial coating is one of the most important for its durability, corrosion resistance, resistance to wear, friction, abrasion and final appearance (colour, brightness...) Electroless nickel can be applied on most metals, carbon and alloy steels, stainless steels, aluminium, copper, bronze...
The entire Chemical Nickel process is carried out by complete immersion of the pieces in a battery of tanks, each with different compositions and missions.
Según el contenido en fósforo en la aleación clasificaremos el deposito de medio (5-9%) o alto contenido en fósforo (10-12%)
This treatment improves the hardness of the base material.
This coating technique is useful to prevent corrosion and dewatering
Subsequent heat treatment allows hardnesses close to those of hard chrome to be achieved
This provides layer consistency throughout the part geometry
It is an environmentally friendly treatment
Can be applied to both conductive and non-conductive materials
