Abstract

A FeCoNiAlTiCrSi high entropy alloy coating was cladding on the surface of Q235 steel by laser using FeCoNiAlTiCrSi as basic alloy powder in which B, C, and Y2O3 were added as a in situ synthesized elements. The results show that the 2mm thickness coating with no crack and pores was prepared under the optimized laser process parameters that the power is 1380W, spot size is 6mm × 4mm, scanning speed is 6mm/s, overlapping rate is 36% and shielding gas velocity is 1.5L/min. The structure is mainly composed of FCC and TiC particle phase, the size of the TiC particle synthesized in-situ is about 0.5µm-3µm. The average microhardness of coating is 450HV0.2, The dispersed TiC particles play the role of strengthening and toughening. The 2 mm thickness FeCoNiAlTiCrSi high entropy alloy coating prepared by this laser cladding method has good hardness and toughness.
