Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum thermischen Spritzen, insbesondere zum Lichtbogenspritzen mit Zusatzwerkstoff (3), der durch einen mittels Elektroden erzeugten Lichtbogen aufgeschmolzen wird, wobei das Druckgas (8) mit hoher Geschwindigkeit durch eine Düse (7) ausströmt und das aufgeschmolze Material des Zusatzwerkstoffes (3) auf eine vorbereitete Oberfläche (1a) spritzt, und wobei erfindungsgemäß das Druckgas (8) mit einer modulierten/pulsierenden Gasströmung hoher Geschwindigkeit erzeugt wird, wodurch ein sich unerwünscht aufbauendes Wirbelgebiet des aufgeschmolzenen Materials im Bereich der Enden des Zusatzwerkstoffes (3) eingeschränkt oder verhindert wird. Die Vorrichtung weist eine Einrichtung zur Erzeugung des Druckgases (8) hoher Geschwindigkeit sowie Mittel auf, durch welche die modulierte/pulsierende Gasströmung hoher Geschwindigkeit erzeugbar ist derart, dass ein Absetzen bzw. Verweilen von Partikeln/Tropfen des aufgeschmolzenen Materials an der Düse (7) und/oder am Zusatzwerkstoff (3) verhindert wird und/oder daran abgesetzte Partikeln/Tropfen gelöst werden.
