Electroless nickel technology receives new treatment

Electroless nickel coatings have been used for decades to protect materials against corrosion and wear, avoiding the use of electrical current during the coating process. The electroless process, however, is limited by the size of the components to be coated, in that large objects cannot be treated in the traditional plating facilities.
Electroless nickel technology receives new treatment
There are specific advantages associated with the application of electroless nickel coatings such as high wear resistance and prevention of product contamination. In order for the process to be effective, however, the target surface must be totally immersed in the plating solution and be free of all contaminants. Consequently, bulky, non-transportable objects are excluded from this process.

A Norwegian SME has devised a method for the in situ electroless nickel coating of such large objects, expanding the applicability of the process. The thinking behind this new methodology is simple enough; instead of bringing the object to the coating facility, the coating facility is brought to the object. The method, termed INSEN, could revolutionise in situ coating techniques and shorten processing times.

INSEN's innovation does not lie solely in the locality of the coating process. The new method uses only one solution for a series of process steps, replacing multiple chemical stages. Furthermore, the coating solution is still suitable for use even after plating of the target object has been completed.

The company has patented the coating method and is seeking commercial/industrial partners for collaborations in this field. The INSEN method has direct bearing in the manufacturing and materials technology industries and could significantly expand the lifetimes of manufacturing materials.
