4. Properties of electroless nickel-boron coatings

The properties of nickel-boron coatings are particularly interesting for a wide range of applications. They derive directly from the chemical composition of these deposits and their growth mode.

4.1 Chemical composition, morphology and structure of deposits

The chemical composition, structure and morphology of nickel-boron coatings are difficult to describe univocally, as there are numerous deposition baths, each leading to a particular deposit with well-defined properties. Indeed, the boron content on the one hand and the reduced stabilizer content (as well as the nature of the latter) on the other strongly influence these properties. Nevertheless, it is possible to group together coatings with similar contents and properties, and to determine trends in their...

Regulations

ELV (End of Life Vehicles).

European Directive 2000/53/EC on end-of-life vehicles stipulates that "materials and components for vehicles put on the market after 1 ^er January 2003 must not contain lead, cadmium, mercury or hexavalent chromium. The tolerance is 0.1% for lead and 0.01% for cadmium, provided that these substances are not intentionally introduced."...
