Abstract
GH3536 superalloy powder was prepared by the plasma spheroidization. The powder characteristics and effects of the plasma power on the percento spheroidization were studied.The phase and morphological properties of the powder were characterized by scanning electron microscope (SEM),Malven M4 particle size and shape analyzer and Leco ON736 oxygen-nitrogen analyzer.The results show that GH3536 fine spherical powder has favorable dispersity, smooth surface and high spheroidizing rate of 99%.The particle size distribution of the powder is narrowed,and the apparent density and tap density are significantly increased,which can meet the requirements of addictive manufacturing.
