Functional coatings as such have the characteristic whereby properties different from the nature of the object to be metallised are conferred to its surface but which are able to satisfy the parameters required by the specific application and as such the product is able to be placed in “function”.
In fact we are referring to categories that are very close together such that they can be catalogued as technical coatings but that take advantage of two entirely different principles. One of these principles is represented by chemical nickel plating which has the advantage of giving uniform thickness regardless of the component’s geometry, good corrosion resistance and is capable of protecting the surface from wear.
The properties of corrosion and wear resistance are also possible using electrolytic processes such as the anodic oxidation of aluminum (traditional and hard) and thick chrome plating.
In essence, it involves processes that are particularly useful for many applications and different ranges of industries.
