Summary:A facile method for synthesis of nano-particles attached spherical alloy powders was established based on plasma spheroidization in this work. Nano-particles attached spherical Ti‐6Al‐4V powder was in situ synthesized by manipulating plasma gas composition. Microstructure and phase composition of nano-particles attached spherical Ti‐6Al‐4V powder were investigated. Results show that the nano-particles are mainly mixtures of AlTi, AlTi3, AlTi2N and TiN with an average size of 85.45 nm. The nano-particles are uniformly distributed throughout the surface of spherical Ti‐6Al‐4V powder, which is ascribed to the vaporization and condensation of raw powder undergoing a steep variation of the temperature.
