Title
(DE) VERFAHREN ZUR HERSTELLUNG EINER ULTRAPHOBEN OBERFLÄCHE AUF BASIS VON WOLFRAMCARBID
(EN) METHOD FOR PRODUCING AN ULTRAPHOBIC SURFACE BASED ON TUNGSTEN CARBIDE
(FR) PROCEDE POUR PRODUIRE DES SURFACES ULTRAPHOBES A BASE DE CARBURE DE TUNGSTENE
Abstract
(DE)
Es wird ein Verfahren zur Herstellung einer Oberfläche mit ultraphoben Eigenschaften beschrieben, bei dem eine im wesentlichen glatte Oberfläche aus Wolframcarbid mittels Laserablation strukturiert wird, wobei entlang der Oberfläche insbesondere periodisch wiederkehrende Vertiefungen gebildet werden, mit einer Tiefe im Bereich von 10 $g(m)m bis 500 $g(m)m, die Oberfläche gegebenenfalls mit einer Haftvermittlerschicht beschichtet und anschliessend mit einem hydrophoben oder oleophoben Überzug versehen wird.
(EN)
The invention relates to a method for producing a surface having ultraphobic properties. According to the inventive method, an essentially smooth surface comprised of tungsten carbide is structured by means of laser ablation, whereby recesses are formed which, in particular, periodically recur along the surface and which have a depth ranging from 10 $g(m)m to 500 $g(m)m. The surface is optionally coated with a bonding agent layer and is subsequently provided with a hydrophobic or oleophobic coating.
(FR)
L'invention concerne un procédé pour produire une surface présentant des propriétés ultraphobes, selon lequel une surface pratiquement lisse, constituée de carbure de tungstène est structurée par ablation au laser. Ledit procédé consiste à ménager des évidements en particulier récurrents le long de la surface, présentant une profondeur comprise entre 10 $g(m)m et 500 $g(m)m, puis à revêtir éventuellement la surface avec une couche d'agent adhésif et à appliquer un revêtement hydrophobe ou oléophobe.
