Abstract

Es wird eine Plasmaspritzvorrichtung vorgeschlagen, deren Brennerkopf (1) mit einem Anodenbasiskörper (2), einem Kathodenbasiskörper (4) und einem dazwischen eingefügten Isolierkörper (3) versehen ist. In den Anodenbasiskörper (2) ein Gaszufuhrkanal (12) eingelassen, der in eine im wesentlichen kegelförmig gestaltete Ausnehmung (13) mündet. Über diesen Gaszufuhrkanal (12) kann ein zwischen einem Pulverzufuhrkanal (9) und der Auslassdüse (6) verlaufender Hohlraum (15) mit einem Gas geflutet werden. Dadurch werden Ansammlungen von Beschichtungspulverpartikeln im Bereich der Auslassdüse (6) weitestgehend vermieden und die Qualität der augetragenen Schicht verbessert..
