PURPOSE: A manufacturing method of alloy/metal powder dispersed with nano ceramic using the high-speed milling machine and the resultant alloy/metal powder dispersed with nano ceramic are provided to make various ceramic powder nano-size and to uniformly disperse the various ceramic powder in metal and alloy base materials. CONSTITUTION: A manufacturing method of alloy/metal powder dispersed with nano ceramic using the high-speed milling machine comprises follows. Ni system or Fe system metal powder and ceramic powder are mixed. The manufactured compound powder is put in the rotating container in a high-speed milling device of contact rotation type along with steel balls. A powder container(4) rotates at high speed in the opposite direction of a rotating shaft of a wall side(3) of a chamber inner guide.
