Effect of CeO<sub>2</sub> doping on microstructure, friction and wear properties of AlCoCrCuFe high-entropy alloys
AlCoCrCuFe high-entropy alloy was fabricated by melting-casting method. The phase structure, microstructure and friction and wear property for this alloy without and with CeO<sub>2</sub> doping were investigated by XRD, SEM, EDS, microhardness tester and friction-wear tester, respectivel...

| description | AlCoCrCuFe high-entropy alloy was fabricated by melting-casting method. The phase structure, microstructure and friction and wear property for this alloy without and with CeO<sub>2</sub> doping were investigated by XRD, SEM, EDS, microhardness tester and friction-wear tester, respectively. The results show that AlCoCrCuFe alloy has BCC+FCC dual phase structure. 1%(mass fraction)CeO<sub>2</sub> addition improves the diffraction peak of AlCoCrCuFe alloy. The microstructure of two above alloys is typical dendrite structure. The interdendrite region is mainly Cu-rich and Ce-rich area, and the dendrite microstructure is layered grid structure of spinodal decomposition. After CeO<sub>2</sub> adding, the microhardness increases from 441.5HV to 475.3HV, and the friction coefficient and the mass loss rate decrease from 0.55 and 1.44% to 0.4 and 1.28%, respectively. |
