Microstructure and Mechanical Properties of Ti(C,N)-based Functional Gradient Cermets Nitriding by Microwave Heating

High Temperature Materials and Processes, 2015
The interaction between nitrogen and titanium carbonitride (Ti(C,N))-based cermets by microwave heating was applied to develop functional gradient cermets. Ti(C,N)-based cermets was densification and nitrided simultaneously above the eutectic temperature,

Effect of Mo2C addition on the formation of core-rim structure and mechanical properties of Ti(C,N)-WC-Mo2C-(Ni, Co) cermet

Journal of Materials Research and Technology, 2023
Ti(C,N)-based cermets with various Mo2C contents (4, 6, 8, 10, 12 and 14 wt%) were fabricated via vacuum hot-pressing sintering. The results showed that the cermets were comprised of coarse hard phase with a core-rim structure and partial fine rimless ...

Towards Self-Lubricating Effect of In Situ Iron Tungstate in Rubbing WC/Mn13 Steel Cermet against a HSS Steel

Lubricants, 2023
We study the mechanism of formation of the multilayer structure of the subsurface regions of WC/Mn13 steel cermets after sliding on a steel disk at speeds from 10 to 37 m/s and contact pressure of 5 MPa in order to elucidate the fundamental role of the ...
