Microstructure and mechanical properties of Cu–Fe-ZTA cermets prepared by vacuum hot pressing sintering

Journal of Materials Research and Technology, 2022
Cermets with Cu and Fe as matrix and zirconia toughened alumina (ZTA) as reinforcement phase were prepared by vacuum hot pressing sintering. Electroless Ni plating was carried out on ZTA particles to improve the interfacial bonding ability between ZTA ...

Macro-gradient structures generated in Ti(C, N)-based cermets with supersaturated WC: an experimental and thermodynamic investigation

Materials Research Letters, 2023
WC is an indispensable constituent when producing Ti(C, N)-based cermets, yet its role on microstructure and the mechanism remain blurred. Herein, based on the CALPHAD approach, we designed and synthesized the cermets containing unsaturated and ...

High temperature oxidation resistance of (Ti,Ta)(C,N)-based cermets [PDF]

, 2016
Cermets based on titanium–tantalum carbonitride were oxidized in static air between 800 °C and 1100 °C for 48 h. The thermogravimetric and microstructural study showed an outstanding reduction in the oxidation of more than 90% when the Ta content was ...

TiCN Cermets with MnFeCoNiCu High Entropy Alloy Binder

Metals, 2023
Cermets are composites of a TiCN hard phase and a metal binder, typically a mixture of Co and Ni. They offer excellent combinations of hardness and fracture toughness as well as bending strength. Due to the current classification of both Co and Ni as CRM
