    Study on Optimization of Process Parameters and Microstructure Properties of Laser-Cladded AlCoCrFeNi<sub>2.1</sub> Eutectic High Entropy Alloy by LI Zansong, WANG Dongsheng

    Published 2025-05-01
    “…In order to investigate the effects of processing parameters on the microstructure and mechanical properties of the AlCoCrFeNi2.1&#x00A0;eutectic high entropy alloy(EHEA), an orthogonal experimental design coupled with a comprehensive-scoring method was used to preliminarily identified the optimal laser cladding conditions.Among the tested combinations, Sample 4 (laser power 1 800 W, scanning speed 360 mm/min, powder-feed rate 2.1 r/min) and Sample 5 (laser power 1 800 W, scanning speed 420 mm/min, powder-feed rate 2.4 r/min)received the highest scores.These two specimens were then subjected to multi-pass, single-layer laser cladding, and their microstructures and mechanical properties were systematically characterized.Results showed that the laser-cladded AlCoCrFeNi2.1&#x00A0;EHEA coating was composed predominantly of dual FCC and BCC phases.In the multi-pass coating, Sample 5 displayed a surface dominated by uniform equiaxed grains,whereas Sample 4 exhibited a mixture of columnar and equiaxed grains with larger, irregular sizes.Further investigations showed that Sample 5 possessed superior microhardness and wear resistance:an average hardness of 323.7 HV1.0,an average friction coefficient of 0.64,and markedly lower wear rate (1.16×10-6&#x00A0;mm3∙N-1∙mm-1) and wear volume (14.4 mm3) than Sample 4.Accordingly, the optimal laser-cladding parameters for AlCoCrFeNi2.1&#x00A0;EHEA were determined to be a laser power of 1 800 W, a scanning speed of 420 mm/min, and a powder-feed rate of 2.4 r/min.…”
