Microstructure and mechanical properties of FeCrNiCoCu(B) high-entropy alloy coatings

摘要：

　　Two kinds of high-entropy alloy coatings of FeCrNiCoCu and FeCrNiCoCuB were deposited on AZ91 magnesium alloy substrate using high velocity arc spraying technology.Microstructure and general mechanical properties of the coatings were investigated with Scanning Electronic Microscope (SEM),X-Ray Diffraction instrument (XRD),microhardness tester and strength bond tester.The results show that the two kinds of coatings exhibit compact layered microstructure and the phase lattice type are both FCC,the microhardness of the FeCrNiCoCu and FeCrNiCoCuB coatings are 414HV0.1 and 342HV0.1 respectively,the bond strength are 36.9 MPa and 33.6 MPa respectively.
