Abstract：The preparation methods of nickel- based superalloy spherical powder mainly include plasma rotating
electrode powder technology (PREP), vacuum induction melting gas atomization method (VIGA), ion atomization
method (PA) and electrode induction gas atomization method (EIGA) etc. This article summarizes the development
status of nickel-based superalloy spherical powders, respectively introduces spherical powder preparation technology,
powder screening and impurity removal, powder-related equipment and company development status, and analyzes
the problems faced by nickel-based superalloy spherical powders. It hopes to provide a reference for the preparation
of high-quality spherical powders.
