Abstract
Bei einem Verfahren zur Herstellung von Formteilen aus
Legierungen, insbesondere aus Nickel-Basis-Legierungen,
Chrom-Basis-Legierungen, Titan-Basis-Legierungen, und
dispersionsgehärteten Legierungen wird ein Pulver der
Legierung oder ein Gemisch aus Pulvern der Legierungs
komponenten mit Hilfe von Thermoplasten, Duroplasten und
Gleitmitteln zu einer spritzfähigen Granulat-Masse aufberei
tet, wobei der Kunststoffanteil ca. 30 bis 50 Volumenprozente
ausmacht. Die Aufbereitung erfolgt dadurch, daß die ver
wendeten Kunststoffe in einem das Basismetall der Legie
rung nicht angreifenden Lösungsmittel gelöst und mit dem
Metallpulver gemischt werden, und anschließend das Lö
sungsmittel abgedampt wird. Danach wird die spritzfähige
Granulat-Masse durch Spritzguß zu einem Formteil verarbei
tet. Durch eine Wärmebehandlung bis 600°C unter Schutzgas
wird der Kunststoff aus dem Formteilentfernt. Anschließend
wird das Teil gesintert. Zwecks Erhöhung der Festigkeit ist
ein heißisostatisches Nachverdichten denkbar. Dadurch las
sen sich mechanische Eigenschaften (insbesondere Swingfe
stigkeit) von Formteilen verbessern, die beispielsweise durch
Feinguß nicht erzielt werden können.
