NICASIL PROCESS is a well known chemical system with a medium level of phosphorus that is suitable to obtain on all kind of processed surfaces a uniform and constant layer, porous-less, adherent and great resistance against corrosion and friction. The resulting coating is a nickel-phosphorous alloy obtained by an auto-catalytic bath.
Since seventies either Nicasil-process or Niploy-process were the most important brands for the electro-less nickel coating here in Italy. In detail, these technological processes, have always captivated the customers of the engineering sectors and so on by their chemical and physical features. Nicasil-process is as well suitable to protect all sorts of metals and their derivatives, then it is useful for decorative patterns because of the amazing aesthetical impact.
In particular, the application concerns:
Iron alloys (Pig iron, alloy steels, stainless steel), Copper and its alloys (Brass and bronze), Aluminium alloys.
The main involved sectors are the following:
Prints for rubber, plastic and glass
The performances of the Nicasil-process coatings are affected by the surface of the basic substrate, proportioned on the thickness they reproduce the basic substrates’ features. Then the resulting performances depend on the thickness and on the thermal treatment as a second step of the process. The thermal treatment increases the hardness of the coating from 500 HV100 (Not hardened) up to achieve the maximum of 1000 HV100.

The absence of the electric transmission which is responsible of the common phenomena of the hydrogen develop on the electrolytic-treated items, reduces the weakness caused by the nascent hydrogen on the substrate.
The high corrosion resistance is mainly due to the crystalline morphology originated by the Nicasil-process, in fact because of the presence of phosphorous the coating presents little porosity. The proportioned nickel atoms induce an higher hardness on the whole surface.
