Cermets and Hardmetals

Abstract

Cermets and hardmetals combine the most favorable characteristics of ceramics and metals, namely the high hardness and elastic moduli of the former, and the ductility and toughness of the latter. [...]

A Review of Research Progress on Ti(C,N)-Based Cermet Binder by Intermetallic Compounds and High-Entropy Alloys

“…Ti(C,N)-based cermet is a kind of metal-ceramic material prepared by the powder metallurgy method using TiC, TiN, and Ti(C,N) as the matrix composition [1][2][3][4], the titanium carbide structure, as shown in Figure 1, Fe-Co-Ni as the binder [5][6][7][8], and other transition metal carbides [9][10][11][12]. Because of its high hardness, excellent wear resistance, low coefficient of friction, and good chemical stability, Ti(C,N)-based cermet has become an important alternative material to cemented carbide and is widely used in cutting and grinding tools [13][14][15][16][17].…”

Microstructure and properties of (Ti, W) C-CoCrNi-xMo cermets

“…In classic (Ti, W) C-based cermets, nickel (Ni) and cobalt (Co) are commonly used as binders. However, the ferromagnetic properties of Ni and Co are unpopular in various fields, especially those requiring non-magnetic materials, such as industrial manufacturing [9] , cutting tools, and medical research [10][11] . Therefore, seeking new binder materials and preparation methods to overcome these challenges is crucial for further expanding the application areas of cermets.…”
