英文摘要	(FeNiCo)-(AlCrSiTi) multicomponent alloy coatings with different contents of alloying components (Al, Cr, Si, Ti) were manufactured by laser deposition. The effect of the alloying components content on the microstructure and mechanical properties of the coatings was investigated. The results show that the content of face-centered cubic (FCC) phase in the coatings decreases gradually and the microstructure is changed from FCC phase+body-centered cubic (BCC) phase to BCC phase dominated with the increase of alloying components (Al, Cr, Si, Ti) content. Moreover, the density of nano-precipitation particles in the BCC phase increases significantly and the average size of the nano-precipitation particles decreases from 97 nm to 36 nm. Meanwhile, with the increase of alloying components content, the area of equiaxed grain microstructure in the coatings increases and the equiaxed grains become much finer, with the minimum average grain size of only 10.8 μm. Furthermore, the microhardness of the coating cross section increases from 271HV0.1 to 718HV0.1. However, the bending strength of the coating decreases from 2208 MPa to 1374 MPa and the maximum bending strain also decreases from 7.3% to 0.47%. © 2021, Journal of Materials Engineering.
