Abstract

In inductive heat treatment, the induction coil design plays an important role in the localization of heat generation. Therefore, the combination of an optimized coil geometry and frequency choice determines the workpiece properties and applicability of close-to-contour hardening for small parts or thin hardened layers. Additive manufacturing of copper alloys in the Selective Laser Melting (SLM) process offers a method to build coils with high design flexibility and precision. Conventional coil manufacturing methods are reaching their limitations due to the conflicting geometry specifications at the applied frequency range. In the present work, a characterization is presented and the performance of an SLM manufactured coil in MHz induction application of small surface hardened wires of steel is examined.

Kurzfassung

Bei der induktiven Wärmebehandlung spielt die Spulengeometrie eine wichtige Rolle, um die Wärme lokal zu generieren. Hierbei bestimmt die Kombination aus einer optimierten Spulengeometrie mit der angepassten Frequenz die späteren Bauteileigenschaften und die Anwendbarkeit einer randschichtnahen Wärmebehandlung von kleinen Bauteilen oder dünnen Schichten. Die Additive Fertigung von Kupferlegierungen im SLM-Prozess (Selective Laser Melting) bietet eine Möglichkeit Spulen mit einer hohen Präzision und Gestaltungsfreiheit zu fertigen. Hier stoßen die konventionellen Herstellungsmethoden an die Grenzen aufgrund der konkurrierenden Anforderungen der Geometrie im verwendeten Frequenzbereich. In der vorliegenden Arbeit werden eine Charakterisierung und die Leistungsfähigkeit einer im SLM-Prozess gefertigten Induktionsspule im MHz-Bereich anhand von randschichtgehärteten dünnen Stahldrähten dargestellt.
