Abstract

Aufgabe der Erfindung ist es, ein Verfahren zur Wärmebehandlung von Wälzlagerbauteilen aus durchgehärtetem, bainitischem Wälzlagerstahl mit Druckeigenspannungen im Randbereich und einem Martensitanteil von höchstens 5% sowie einem Restaustenitanteil von höchstens 3% so zu gestalten, dass die durch die Wärmebehandlung erzielbare Härte in den Randbereichen des behandelten Werkstückes wenigstens 60 HRC beträgt. Dazu wird die Wärmebehandlung zweistufig durchgeführt, wobei das Werkstück von der Austenitisierungstemperatur ausgehend zunächst in einem Salzbad, dem mindestens 0,5 % Wasser zugesetzt wurden, und das eine Temperatur leicht unterhalb der Martensit-Starttemperatur aufweist, abgeschreckt und solange gehalten wird, bis ein Temperaturausgleich eingetreten ist und wobei das Werkstück anschließend in ein zweites Bad, dessen Temperatur geringfügig über der Martensit-Starttemperatur liegt, umgesetzt und über der Martensit-Starttemperatur gehalten wird.
