Electroless (chemical) Nickel-Phosphorus Plating is the most important catalytic process used in the last two decades.
LEGOR has three types of coatings:
Some of the most important characteristics of these coatings are:
The properties of the coatings depend on the quality and content of phosphorus. The coatings with low phosphorus content are crystalline and hard, so they have a high ware resistance. On the other hand, the high phosphorus content coatings are amorphous and have a high corrosion resistance.
Generally, all the types of coatings have good adherence. Though, the adherence properties depend on some parameters as are the thickness of the layer, phosphorus content, heat treatment and the ductility of the substrate.
The nickel-phosphorus coatings are self-lubricating and have a good friction coefficient.
A very important and unique characteristic of the electroless coatings is the uniformity of the layer on the same surface; the electroless coatings emulate perfectly the substrate surface.
