Description

Wärmebehandlung von aus Sintermetall hergestelltem Kolbenring Die Erfindung betrifft die Härtung gepreßter und gesinterter Kolbenringe, die gemäß Patent 942 814 der Aufkohlung im Einsatzverfahren unterworfen werden.Heat treatment of piston ring made of sintered metal Die The invention relates to the hardening of pressed and sintered piston rings according to Patent 942,814 can be subjected to in-service carburization.

Zur Erzielung der erforderlichen elastischen Eigenschaften, die insbesondere an Kolbenringe für Verbrennungskraftmaschinen gestellt werden müssen, wird erfindungsgemäß der eingesetzte Ring nach der Einsatzbehandlung gehärtet und gegebenenfalls auch angelassen.To achieve the required elastic properties, in particular must be placed on piston rings for internal combustion engines, according to the invention the ring used hardened after the use treatment and, if necessary, also left on.

Das Härten erfolgt in an sich bekannter Weise, das Abschrecken in Wasser, Öl oder sonst einem Härtemittel, entweder unmittelbar nach dem Einsetzen oder nach nochmaligem Erhitzen. Durch das Anlassen kann dem gehärteten Ring eine unerwünschte zu hohe Härte genommen werden.Hardening takes place in a manner known per se, quenching in Water, oil or some other hardening agent, either immediately after insertion or after reheating. Tempering can cause a unwanted excessive hardness can be taken.
