Mechanical properties and features of erosion of cermets

Effects of WC particle size on sintering behavior and mechanical properties of coarse grained WC–8Co cemented carbides fabricated by unmilled composite powders

“…The properties of binder phase play an important role in the wear behaviors especially for coarse grained WC-Co cemented carbides due to their relatively larger thickness of binder phase than fine grained WC-Co cemented carbides [52]. During the friction process, the impact energy of carbide particles transmits to binder phase and causes stress accumulation, thus leads to the debris and debonding of binder phase.…”

The effect of fluid viscosity on the erosion wear behavior of Ti(C,N)-based cermets

“…The material failure initially begins in the binder phase [17]. During the erosion process, the impact energy of solid particles transmits to the binder phase due to the high stiffness of the ceramic phase and the relatively excellent ductility of binder phase.…”

Thermal stress analysis of HVOF sprayed WC–Co/NiAl multilayer coatings on stainless steel substrate using finite element methods

“…The whole model was divided into by 1000 elements and 1066 nodes. The thermal and mechanical properties of WC-Co, NiAl coatings and substrate are given in Tables 2 [15][16][17], 3 [18][19][20] and 4 [21][22], respectively. Boundary conditions for heat transfer and stress analyses used for finite element modeling are shown in Fig.…”
