Abstract

Es wird ein weichmagnetischer, formbarer Verbundwerkstoff vorgeschlagen, der ein weichmagnetische Eigenschaften aufweisendes Pulver und mindestens eine Silizium enthaltende Verbindung oder eine Aluminium enthaltene Verbindung oder eine Bor enthaltende Verbindung aufweist, wobei die Körner des Pulvers mit der Siliziumverbindung, der Aluminiumverbindung oder der Borverbindung beschichtet sind. Weiter wird ein Verfahren zur Herstellung eines solchen weichmagnetischen Verbundwerkstoffes vorgeschlagen, wobei nach einem Formpreßschritt des Verbundwerkstoffes der Formpreßling einer thermischen Behandlung unterworfen wird.
