processo de aplicação de um revestimento de um material termoplástico a um substrato feito de um material polimérico

A method applies a coating (17) of a thermoplastic material on a substrate (11) made of a polymeric material, with the thermoplastic material and the polymeric material being incompatible. Firstly, the substrate and/or the powder are exposed to a plasma discharge (12) or the reactive gas stream resu...

Beschreibung
Zusammenfassung:	A method applies a coating (17) of a thermoplastic material on a substrate (11) made of a polymeric material, with the thermoplastic material and the polymeric material being incompatible. Firstly, the substrate and/or the powder are exposed to a plasma discharge (12) or the reactive gas stream resulting therefrom in order to obtain a plasma treated surface layer (14) introducing compatibility at the interface between substrate and coating. Secondly, laser cladding (15) the powder (16) on the substrate is conducted in order to form a coating on the substrate.
