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...
