Super alloy was widely used in a variety of industry fleld such as aeronautics and astronautics, and plasma deposition manufacturing has provided an efiective way in fabricating refractory and intractable parts e.g., super alloy parts directly from their digital models. How- ever, there is much di-culty in fabricating parts with large obliquity because of the ∞owing of molten pool caused by gravity fleld. In this paper, an innovated method named electromagnetic- compressed plasma deposition manufacturing is presented which employs the electromagnetic fleld to decrease the efiectiveness of the ∞owing of molten pool. The result shows that the com- plicated parts with big overhang structure and large obliquity could be fabricated under proper tool path and the help of electromagnetic. Some parts with complex shape were trial manufac- tured which proves that electromagnetic-assisted plasma deposition manufacturing is a promising technology in direct rapid manufacturing.
