Abstract

Die Erfindung bezieht sich auf ein Verfahren zum elektrostatischen Beschichten von Werkstücken mit Pulvermaterialien. Um in einem Arbeitsgang eine relativ große Schichtdicke zu ermöglichen, wird vorgeschlagen, Pulverpartikel mit unterschiedlicher elektrischer Ladung gleichzeitig oder abwechselnd aufzutragen. Das Verfahren ist zum Auftragen von ein- oder mehrkomponentigen Beschichtungsmaterialien geeignet.
