【摘要】 本研究采用静电自组装（ESA）技术解决了激光增材制造中06Cr19Ni10（7.9g/cm3）与La₂O₃（6.5g/cm3）因密度差异导致的增强相偏析问题，成功实现La₂O₃纳米颗粒在06Cr19Ni10粉末表面的均匀包覆。通过激光增材制造（LAM）技术在Q235钢基板上制备La₂O₃梯度增强的06Cr19Ni10-La₂O₃合金，研究了La₂O₃含量（0-1.5wt.%）对显微组织演变及室温力学性能的影响机制。更多还原

【Abstract】 In this study,electrostatic self-assembly （ESA） technology was used to solve the problem of enhanced phase segregation caused by density difference between 06Cr19Ni10 （7.9g/cm3） and La₂O₃ （6.5g/cm3） in laser additive manufacturing,and successfully achieved uniform coating of La₂O₃ nanoparticles on the surface of 06Cr19Ni10 powder.A 06Cr19Ni10-La₂O₃ alloy reinforced by La₂O₃ was prepared on Q235 steel substrate by laser additive manufacturing （LAM） technology.The influence of La₂O₃ content （0-1.5 wt.%） on microstructure evolution and mechanical properties at room temperature was studied.更多还原
