    • PROBLEM TO BE SOLVED: To solve the problem that rapid cooling treatment is required for the formation of an amorphous alloy, and a method of coating the surface of an object to be worked therewith is not developed as yet.
      SOLUTION: A thick cooling dome 1 having a high thermal conductivity and a high capacity and, e.g., made of copper is connected to a centrifugal casting machine for rapid solidification, a tubular object to be worked is beforehand inserted and fixed therein and is rotated at a high speed, an amorphous alloy molten metal melted by a high frequency coil is injected toward the inside face of the object to be worked from a nozzle, and simultaneously, the nozzle is pulled up to the axial direction at a fixed speed, and coating is performed.

    • PROBLEM TO BE SOLVED: To solve the problems that, regarding amorphous bulk metal glass and extra-fine crystal cast parts, though there is a need of rapid cooling simultaneously with the pouring of molten metal, a rotary mold in the conventional centrifugal casting machine has no rapid cooling function, and further, that the plan of a mold for rapid solidification paying on the advantage of a near net shape finishable from melting in a centrifugal casting process into a final product dimensional shape such as a pipe and hollow screw parts at a high speed has not been proposed.
      SOLUTION: The center of a mold body 1 made of a material having high thermal conductivity such as copper and having a columnar shape is provided with a sprue 2, from the sprue 2, radially; a molten metal guide passage 3 and a product mold 4 at the tip thereof are worked; the same is vertically cut in two along the central line of the molten metal guide passage; they are inserted into a base 5 on a bottomed cylinder fixed to the rotary shaft A in a centrifugal casting machine, and a disk-shaped cover 6 whose center is provided with a sprue hole is fixed to the base 5, so as to be a rotary mold.
