Method for performing in-line metal coating electrolessly by spraying on substrate as front surface treatment, and apparatus for realizing the method

摘要

A method of metallizing the surface of a substrate electrolessly, by spraying one or more oxidation-reduction solutions thereonto. The steps of this method include: a) physical or chemical treatment to reduce the surface tension of the substrate before metallization; b) electroless metallization of the surface of the substrate treated in step a), by spraying one or more oxidation-reduction solutions in the form of one or more aerosols thereonto; and c) formation of a top coat on the metallized surface. Compact devices for implementing this method and the products obtained are also disclosed.
