“…The carbides of Cr were commonly found in the HEA containing both Cr and C. 37,38 Previous studies have reported that the mechanical and tribological properties were improved with the addition of Cr 3 C 2 . 39,40 The carbides of Cr have been verified with high hardness, strength and excellent thermal stability, which could impede the dislocation motion and strengthen the composite significantly. 40 Thus, the outstanding tribological properties of the HEA/0.6 wt% GO composite were also attributed to the strengthening effect of the carbide of Cr in this study.…”

“…Thus Ag will not react with other elements and remain as Ag in composites. Because of the rapid sintering of SPS technique, the Cr 3 C 2 decarburizes forming Cr 7 C 3 [23]. Compared to Cr 3 C 2 , Cr 7 C 3 has higher thermal stability, strength and wear resistance, which can improve the strength of composites.…”

CoCrFeNiMn high entropy alloy (HEA) matrix composites with Cr3C2 reinforcement (10 wt%) and different mass friction of Ag lubricant (10, 15 and 20 wt%) were produced by spark plasma sintering. The composites consist of HEA’s FCC phase, Cr7C3 phase and Ag phase, and the microstructures of composites are dense and uniform. The ultimate plasticity strain and fracture toughness improve with the addition of Ag increasing at room temperature. The composites exhibit excellent self-lubricating and wear resistance below 400 °C, and the composite with 20 wt% Ag content has the lower friction coefficient and wear rate. The Ag addition exhibits positive role in improving the wear behavior at medium-low temperatures. The main wear mechanisms of the composites are micro-cutting and abrasive wear at low temperatures. At high temperatures, the oxide tribo-layer generates on the wear surface and deeply torn. Oxide wear and surface deformation are the main wear mechanisms.

“…NiCr-Cr3C2 composites ceramic coatings are widely used for surface strengthening of components due to high temperature resistance, wear resistance and corrosion resistance (12,13) . Huang et al reported that the Ni based composite coatings have been obtained by using the plasma spray welding process and mixed powders (NiCrBSi + NiCr-Cr3C2 + WC)., exhibited enhance the coating hardness and good mechanical properties (14) .…”

The surface properties and cavitation erosion performance of NiTi/NiCr-75%Cr3C2 composite coatings on AISI 304 stainless steel substance by atmospheric plasma spraying (APS) at different hydrogen gas flow rate were investigated. Composite coatings were characterized for microhardness. Microstructure of the cross section of composite coatings were investigated by scanning electron microscopy (SEM) with energy-dispersive X-ray spectroscopy (EDS). Caivation erosion test was finished by ultrasonic stretching vibration caviation test machine. The results show that when the hydrogen gas flow rate is 3L/min and 6L/min, the microhardness of coatings are respectively 640 HV and 730 HV at a load of 100 g and a dwell time of 15s condition, and the composite coatings by APS generates porosity and were oxidized. The cavitation erosion resistance of composite coatings is better than that of nodular cast iron. As the hydrogen gas flow rate increases, the microstructure of composite coating deposited by APS has lower porosity, and the better cavitation erosion resistance.
