of Al2O3 nano-particles on properties of CoCrNi LPBF part Experiment This study used CoCrNi alloy powder and Al\u2082O\u2083 powder as raw materials. CoCrNi alloy powder was prepared by vacuum gas atomization, and the powder particle size range was 15-53 \u03bcm. The particle size of Al\u2082O\u2083 powder was 38-74 \u03bcm. After the raw material powders were mixed, they were processed on the LPBF additive manufacturing system. Chemical composition of CoCrNi: Morphology of CoCrNi: Microstructure analysis: After adding Al2O2, the grains in the CoCrNi matrix are significantly refined, and a large number of nano-scale Al2O2 precipitates are formed.
