5. Effect of heat treatment on electroless nickel-boron coatings

As expected, electroless nickel-boron coatings without special treatment show a metastable structure that does not correspond to that predicted by the nickel-boron phase diagram for these boron contents. This is because the solubility of boron in nickel at room temperature is extremely low, and numerous intermetallic compounds (such as Ni ₂ B, Ni ₃ B, Ni ₄ B ₃ ...) can be formed as a function of the boron content of the mixture

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."...
