Cermet material

Cermet is a hybrid material having the hardness of ceramic and the toughness of metal. Hard pArticles are often made of Titanium carbide (TiC), titanium nitride (TiN), or titanium carbonitride (TiCN), with nickel, cobalt, and molybdenum acting as binders.

Cermet synthesis is a difficult process that requires a combination of optimal synthesis methods and processing parameter adjustment to attain desired features. This research looks at some significant synthesis procedures and how they affect the final properties of cermets.


Cermet material is a ceramic-metal composite that contains a hard ceramic phase as well as a metallic binding phase. These materials are refractory and chemically resistant in general. They are distinguished by their high temperature resistance, hardness, and plastic deformation ability, making them appropriate for a wide range of applications such as machining and cutting tools, extrusion dies, wear-resistant coatings, and so on.

The ceramic phase in a cermet is commonly made of tungsten carbide (WC), titanium carbide, or titanium carbonitride (TiC), and may also contain tungsten, molybdenum, or vanadium oxides, nitrides, or carbonitrides. Cobalt or nickel and their alloys are commonly used as metal binders. The addition of a metal binder to a cermet system can improve the material's mechanical and tribological performance.

Because of their high hardness, bending strength, and wear resistance, WC-based cermets are a popular choice in cutting tools. They are, nevertheless, fragile and have poor interfacial bonding with the binder. This may have an impact on their sintering and machining capabilities. To prevent such problems, WC-based ceramics are frequently reinforced with tungsten or titanium nitride (WNT) to increase mechanical characteristics and decrease brittle fracture [5,6,9].

Because TiCN-based cermets have higher tensile strength and toughness than other carbide grades, they are more widely employed in cutting tools. They can be improved further by adding Ni or Co metals, which can help improve oxidation and corrosion resistance.

Another benefit of WC-based ceramics is their low cost and widespread availability, making them perfect for mass production. They're also commonly employed in industrial components like bearing seal rings and pump rotors.

Some cermets have been demonstrated to offer superior thermal stability in addition to their tribological capabilities. For example, WC-based ceramics based on ZrTiN and Al2O3 have been demonstrated to retain strength even when subjected to high temperatures. Under typical working circumstances, they can also withstand oxidation and corrosion.

Cermets' tribological and mechanical qualities are determined by their composition, mean free path of the binder, and ceramic particle distribution. A variety of additive manufacturing technologies, such as selective laser melting (SLM), an advanced AM production approach that combines powder metallurgy and laser technology, may manage these characteristics.
