“…Depending on the H a /H m ratio, distinction should be made between “hard” and “soft” erosion. Erosion rate of hardmetals and cermets with SiC particles exceeds, as expected, by a factor of about 10 erosion rate with silica (SiO 2 ) abrasive [ 72 , 75 , 76 , 81 , 83 , 84 ].…”

“…Solid-particle erosion tests of cermets have been prevalently performed using four-channel centrifugal accelerator where up to 15 specimens can be eroded under identical conditions [ 34 , 37 , 48 , 58 , 60 , 64 , 65 , 70 , 71 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 79 , 80 , 81 , 82 , 83 , 84 , 85 , 86 ].

Similar to the work in [ 67 ], it was also shown that there is no consistent correlation between the erosion rate and

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.
