“…When the addition of Cr 3 C 2 excess 1 wt%, it can be seen that some TiN particles with incomplete rim phase increase unceasingly from Figure (as shown in yellow circle), which result in subdued wettability. Therefore, TiN particles of cermet D and E grow slightly than cermet C. This formation of incomplete rim phase is believed to be due to increasement of undissolved TiN particles by adding more Cr 3 C 2 , resulting in decreasing precipitation amount of rims on TiN particles . The simple distribution of grain size is shown clearly in Figure , which is consistent with the explanation above.…”

“…Cr 3 C 2 has a priority to dissolve into metal binder than TiN . Thus, the number of undissolved fine TiN particles will increase as increased Cr 3 C 2 can reduce the solubility of TiN in metal binder . These fine TiN particles are diffused easily by heavy elements (W) during sintering process.…”

“…In Ti (C, N)‐based cermet systems, Cr 3 C 2 is often used as an additive to enhance sintering behavior, the abrasion, and corrosion resistance . Besides, more denser and finer microstructure can be obtained by grain refinement with Cr 3 C 2 addition.…”

TiN‐based cermets with different Cr3C2 addition were prepared by conventional vacuum sintering. Effect of Cr3C2 on microstructure and properties of TiN‐based cermets were discussed. Owing to the formation of sound rims on TiN cores, ultrafine TiN‐based cermets with more uniform microstructure and finer grains were obtained with 1 wt% Cr3C2. When the added Cr3C2 content enhanced from 0 to 2 wt%, the transverse rupture strength (TRS) and fracture toughness increased firstly and then decreased, while the hardness increased monotonically. For the experimental conditions considered, the cermet with 1 wt% Cr3C2 addition had optimal combination of hardness (91HRA), fracture toughness (14.7 MPa m1/2) and TRS (2123 MPa).

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.

“…These complications may have prevented concluding general models and led researchers to tackle specific conditions independently. This may explain the availability of plenty of literature studying wear behavior of specific materials, such as those of Harsha and Sanjeev, 6 Wan et al, 7 and Trevino et al 8 Even for the same material, the erosive wear mechanism can change according to service conditions. The study of Wensink and Elwenspoek 9 showed that there is a great possibility of transition from brittle to a form of ductile erosion.…”

As the mechanism by which material is lost from ductile surfaces during solid particle erosion is still a matter of scientific debate, the work presented in this paper is aimed at trying to shed more light on the mechanism by which material is detached from ductile surfaces during solid particle erosion. Moreover, validating some of the most widely accepted models that predict erosive wear rate will form part of the paper. A specially designed test rig was used to facilitate test condition of an extensive experimental program. Results of the test program showed that plastic strain accumulation is largely responsible for material loss from ductile surfaces, even at cute impact angles. The key to this finding is the drop of erosive wear upon impact angle reversal indicates. It has been shown that none of the most widely accepted models of erosive wear could explain the result obtained under condition of impact angle reversal.
