The Microstructural Development of Laser-Powder-Bed-Fusion Manufactured Tungsten Carbide – Cobalt Hard Metals
-
T. Schubert
Abstract
As a result of their outstanding properties hard metals offer great potential in the tool industry. They are however expensive and geometrically limited when manufactured using conventional machining techniques. Additive manufacturing has the possibility to revolutionise the manufacture of such tools. The composition of hard metals consisting of a hard component within a binder phase in combination with laser based additive manufacturing can produce particular effects in the microstructural development of such materials. This article describes those particular microstructural developments which can be achieved in the powder metallurgical additive manufacturing of hard metals.
Kurzfassung
Auf Grund ihrer herausragenden Eigenschaften bieten Hartmetalle hohes Potenzial für die Werkzeugindustrie, sind aber mittels spanender Fertigung sehr teuer und geometrisch nur eingeschränkt herstellbar. Die Additive Fertigung kann die Werkzeugherstellung revolutionieren. Die Zusammensetzung der Hartmetalle aus Hartstoff- und Binderphase in Kombination mit der laserbasierten additiven Fertigung zeigt empfindlichen Einfluss auf die Gefügeausbildung. Der Artikel beleuchtet die Eigenheiten der Gefügeausbildung von Hartmetallen bei der pulvertechnologischen additiven Fertigung.
