What is a sintered carbide?

Cemented (or sintered) carbides, known collectively in most parts of the world as hard metals, are a range of very hard, refractory, wear-resistant alloys made by powder metallurgy techniques. The minute carbide or nitride particles are cemented by a binder metal that is liquid at the sintering temperature.See all results for this questionWhat are the properties of cemented carbides?The properties of cemented carbides are given by the combination of vastly different constituents, e.g., soft and ductile Co-based binder with hard and wear resistant WC or cubic carbides [ 10, 11 ].See all results for this questionWO1997040203A1 - Sintering tray - Google PatentsThe present invention discloses a method of sintering of cemented carbide or cermet bodies lying on graphite trays.
