1. Verfahren zum Aufbringen eines dauerhaften Wärmesperrüberzugs auf ein metallisches Substrat, beinhaltend die Schritte
a) Herstellen einer sauberen Substratoberfläche,
b) Auftragen eines metallischen Verbindungsüberzugs, der eine Zusammensetzung hat, die aus 15-40%Co, 10-40%Cr, 6-15%Al, 0-2%Hf, 0-7%Si, 0,01-1,0%Y, Rest im wesentlichen Ni besteht, durch Plasmaauftrag in Luft bis zu einer Dicke von 0,127-0,381mm (0.005-0.015 in).
c) Auftragen eines keramischen Überzugs aus Zirkondioxid, stabilisiert mit 6-8 Gew.-% Yttriumoxid, durch Plasmaauftrag in Luft bis zu einer Dicke von 0,254-0,381 mm (0.010-0.015 in.).
2. Gasturbinenbrenner aus Blech, der einen Wärmesperrüberzug auf wenigstens einem Teil hat, mit
a) einer großen, komplexen Blechbaugruppe, die wenigstens eine Gesamtabmessung hat, welche 30 cm (one foot) übersteigt,
b) einem plasmagespritzten NiCoCrAlY-Verbindungsüberzug auf wenigstens einem Teil der Blechbaugruppe,
c) einem festhaftenden plasmagespritzten Zirkondioxidüberzug, der 6%-8% Yttriumoxid enthält,
wobei das Gebilde im wesentlichen unverzogen ist, weil es ohne zugehörige Vor- oder Nachwärmebehandlungen in Luft plasmagespritzt worden ist.
