Abstract

Bei einem Verfahren zur Herstellung eines wärmebelasteten Bauteils (1) einer Wärmekraftmaschine weist das Bauteil (1) Kühlkanäle (2, 10) auf und wird mittels einer Gussform hergestellt.In a method for producing a heat-loaded component (1) of a heat engine, the component (1) has cooling channels (2, 10) and is produced by means of a casting mold.

Das Verfahren umfasst folgende Schritte:
- Herstellung eines nichtmetallischen Körpers (8),
- Anordnen des nichtmetallischen Körpers (8) in der Gussform,
- Einbringen von geschmolzenem metallischen Werkstoff in die Gussform und
- Entfernen der Gussform.The method comprises the following steps:
- production of a non-metallic body (8),
Arranging the non-metallic body (8) in the mold,
- Introduction of molten metallic material in the mold and
- Remove the mold.

Bei einem wärmebelasteten Bauteil (1) einer Wärmekraftmaschine weist das Bauteil (1) Kühlkanäle (2, 10) und einen nichtmetallischen Beschichtungskörper (8) auf, welcher mittels der Kühlkanäle mit Kühlfluid versorgt wird.In a heat-loaded component (1) of a heat engine, the component (1) has cooling channels (2, 10) and a non-metallic coating body (8), which is supplied with cooling fluid by means of the cooling channels.

Auf der Oberfläche des metallischen Grundkörpers des Bauteiles (1) sind Halteelemente (16) mit Hinterschneidungen (18) angeordnet, und diese Halteelemente (18) sind mit dem eine offenporige Porosität aufweisenden nichtmetall i-schen Beschichtungskörper (8) umgeben.
