CoCrFeMnNiNbx (x = 0, 0.25, 0.5, 0.75, and 1.0) high-entropy alloy coatings were prepared on the AISI 1045 steel substrate surface by laser cladding to explore effects of different Nb content microstructure, microhardness, wear resistance, corrosion resistance high entropy coatings. The microstructure CoCrFeMnNi was composed single face-centered cubic (FCC) solid-solution phases without addition. coating mainly a dual-phase structure FCC Laves after addition transformed from hypoeutectic eutectic hypereutectic compositions. microhardness increased gradually with increase content. When x 1, average optimal (416.54 HV0.5), which 2.21 times that Nb0. content, volume decreased 0.0739 0.0145 mm3. primary mechanisms responsible for friction identified as adhesive abrasive wear. first then passivation film stablest densest, resistance. results in work provide theoretical reference preparing
