“…Values, obtained by both methods, must be related to as correspondent with a composite structure, as the sizes of the indentation marks exceeded the sizes of the reinforcement and matrix areas in both cases. The more remarkable effect of hardness increment in the case of TiC-NiMo particles reinforced coating in comparison with Cr 3 C 2 -Ni reinforced one can be induced by a higher hardness of the TiC-NiMo cermet (1415 HV [ 12 ]) in comparison with the Cr 3 C 2 -Ni one (980 HV [ 13 ]). …”

In the current article, high-velocity oxy-fuel (HVOF) sprayed composite powder TiC-NiMo and Cr 3 C 2 -Ni cermet particles reinforced self-fluxing alloy matrix (FeCrSiB) coatings were studied. The actual content of the reinforcement in the sprayed coatings was smaller in comparison with the feedstock powders. Cermet particles were deformed at the impact with the substrate, deformation was more remarkable in the case of the TiC-NiMo particles. Sprayed coatings exhibited a structure with a number of defects, like voids and cracks, whereas the latter were more pronounced in reinforced coatings. Despite the bigger number of defects, cermet particles reinforced coatings had up to 1.2 times higher surface hardness than the unreinforced coating. TiC-NiMo particles reinforced coating demonstrated 1.8 times higher sliding wear resistance than the unreinforced coating. Cr 3 C 2 -Ni particles reinforced coating showed 1.3-2.8 times higher sliding wear resistance in comparison with the unreinforced coating, depending on the series of tests. Addition of cermet particles allowed to increase the resistance of the FeCrSiB matrix to deformation and scuffing.

“…The chemical composition of reference Cr 3 C 2 -based cermet powder (Amperit 588.074, H.C. Starck) is included. For developing TiC-20%NiMo powder, the optimal ratio for carburization TiO 2 :C was found to be 4:1 as well as the amount of NiMo binder and Ni:Mo ratio (2:1) [24]. The constituent powders were subjected to high energy milling in a conventional ball mill with WC-Co hardmetal lining and WC-Co balls (balls-to-powder ratio 20:1) for 72 h. Isopropyl alcohol was used as wetting agent.…”

The aims of this study were: (1) to produce composite coatings by high velocity oxy fuel (HVOF) spraying with steel matrix reinforced by cermets (a) Cr3C2–20%Ni and (b) TiC–20%NiMo, manufactured by mechanically activated synthesis (MAS); (2) to synthesize in situ a carbide reinforcement for iron matrix from a mixture of titanium and carbon during HVOF reactive thermal spraying (RTS); (3) to compare the wear resistance of produced coatings. As a reference, HVOF sprayed coatings from commercial Cr3C2–25%NiCr (Amperit 588.074) and AISI 316L were utilized. Study of microstructure revealed the inhomogeneity of the Cr-based MAS coating; the Ti-based MAS coating had typical carbide granular structure, and the Ti-based RTS coating possessed elongated structures of TiC. The X-ray diffraction revealed two main phases in the Cr-based MAS coating: Cr3C2 and austenite, and two phases in the Ti-based coatings: TiC and austenite. Among the studied coatings, the Cr-based MAS coating demonstrated the highest low-force hardness (490 HV0.3). During the abrasive rubber wheel test (ASTM G65), the Ti-based MAS coating showed the best wear resistance, followed by Cr3C2–25%NiCr and Ti-based RTS coating. In the abrasive–erosive test (GOST 23.201-78), the Ti-based MAS coating was 44% better than Cr3C2–25%NiCr coating. The Ti-based RTS coating was 11% more wear resistant than the reference Cr3C2–25%NiCr coating.

“…Modifications of standard tests are also widely employed [ 51 ]. These rotating wheel abrasive wear tests performed in agreement with standards or using their modified versions have been widely employed in the studies of wear behavior of cermets [ 37 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 ]. The most common abrasive used in the tests is silica (SiO 2 ).…”

“…In the laboratory tests, the conditions employed should be relevant to the real life conditions. The three-body abrasion of cermets using SiO 2 as an abrasive is described in [ 37 , 56 , 58 , 59 , 60 , 61 , 62 , 63 , 64 ].

Abrasion and Erosion Resistance of Cermets: A Review

WC-based hardmetals are employed widely as wear-resistant ceramic–metal composites for tools and wear parts. Raw materials supply, environmental concerns and some limitations of hardmetals have directed efforts toward development of alternative wear-resistant composites–cermets. We present a current state of knowledge in the field of ceramic-rich (≥50 vol%) cermets behavior in abrasion and erosion conditions, which are the dominant types of wear in many industrial applications. Distinction is made between two-body and three-body abrasion, solid-particle erosion, and slurry erosion. Cermets, in particular TiC-, Ti(C,N)- and Cr3C2-based composites and hardmetals, are compared for their abrasive and erosive wear performance and mechanism. The review enabled formulation of tribological conditions in which cermets may be comparable or have potential to outperform WC-Co hardmetals. Hardmetals, in general, outperform cermets in abrasion and solid-particle erosion at room and moderate temperatures. However, cermets demonstrate their potential mainly in severe conditions—at elevated temperatures and corrosive (oxidation, electrochemical corrosion) environments.
