Cermet - Wikipedia
Cermets are also used in machining on cutting tools. Cermets are also used as the ring material in high-quality line guides for fishing rods. A cermet of depleted fissiable material (e.g. uranium, plutonium) and sodalite has been researched for its benefits in the storage of nuclear waste.
A Science-Based Understanding of Cermet …
16-2-2020 · Common defects found in cermet vias were characterized based on the ability of subsequent processing techniques (isopressing and firing) to remove the defects. Non-aqueous spray drying and mist granulation techniques were explored as alternative methods of creating CND50, the powder commonly used for dry pressed parts.

Cermets - An introduction - Explain that Stuff
Cermets offer a perfect solution in components such as resistors and vacuum tubes (valves). Crudely, we can think of cermet resistors as a mixture of an insulator (the ceramic matrix) and a conductor (the metal particles), with the type and relative proportions of the two "ingredients" (ceramic and metal) determining the ultimate resistance.
US8268234B2 - Cermets from molten metal …
New cermets with improved properties and applications are provided. These new cermets have lower density and/or higher hardness than B4C cermet. By incorporating other new ceramics into B4C powders or as a substitute for B4C, lower densities and/or higher hardness cermets result. The ceramic powders have much finer particle size than those previously used which significantly reduces stone size ...

Processing and analysis of FeNbC cermets - …
Cermets, especially hard metals are materials of wide application in tools due to its excellent properties like hardness and toughness. The aim of this work is to analyze cermets composed mainly of Fe, NbC, and different Al contents, materials under development supplied by CBMM (Companhia Brasileira de Metalurgia e Mineração), in its characteristics and processing.
Friction Stir Processing of Cast Iron Using Cermet …
With the aim of developing a durable tool for friction stir processing (FSP) of cast iron, the durability of a Ti (C,N)-Ni cermet tool has been investigated and compared with that of a WC-Co cemented carbide tool. Results of exposure tests in air revealed that the WC-Co cemented carbide sample oxidized rapidly above 973 K, whereas the cermet material showed little oxidization even after ...
