Electroless Nickel

Electroless Nickel

DURNI-COAT®, also known as DNC, is a surface treatment that is tuned to material and their processing and application. The main purpose of the DNC surface treatment is to provide machine components in all sectors of industry with protection against wear and corrosion, while at the same time fulfilling other application demands.

The electroless deposition of DURNI-COAT® layers is based on a reduction into metallic nickel of the nickel ions present in the aqueous process solution. The chemical reacting agents and formulators of the electrons required in this process are the hypophosphite ions in the solution. These agents transform themselves, by oxidation in the course of the reaction, into orthophosphite and are also responsible for the phosphorus content of the deposited DURNI-COAT ® layers.

Suitable Alloys

The range of base materials suitable for treatment with DURNI-COAT® includes most of the industrial used metals as well as plastics.
