摘要： PURPOSE:To form a sprayed deposit with superior adhesive strength by irradiating the surface of a base material with high-energy beam in a reduced-pressure nonoxidizing-gas atmosphere to form the surface part of the base material into molten state and simultaneously spraying a thermal spraying material in a molten state in the form of a jet. CONSTITUTION:The inside of a treatment chamber 4 to which a base material 1 is provided is regulated to an atmosphere of reduced-pressure nonoxidizing gas 7 by means of a nonoxidizing gas-feeding hole 6 and a pressure-reducing hole 5. Subsequently, the surface of the base material 1 is irradiated with a high-energy beam 9 from a high-energy beam-producing device 8 so as to be formed into a molten state 1', and, directly after or simultaneously with the above high-energy beam 9 irradiation, a jet 11 of thermal spraying material previously formed into molten or semimolten state is sprayed on the part of the above molten state 1' by means of a thermal spray gun 10. The above operation is performed continuously, and the base material 1 is moved at the prescribed velocity. By this method, a sprayed deposit 2 having an intermediate layer 3 having a mixed structure consisting of the base material 1 and the jet 11 of thermal spraying material can be formed, by which the adhesive strength of the sprayed deposit 2 can be improved.

摘要： PURPOSE:To cast continuously and stably a thin plate having good quality by installing airtightly a vessel of the type which is open on the lower side in the top edge part of a tundish disposed therein with rolls having a large diameter and a small diameter, and supplying an inert gas therein. CONSTITUTION:The solidified shells 9 and 10 formed by cooling a molten metal 3 as a result of contact with the surfaces of water-cooled rolls 1 and 2 are united to one body at a point P (the nearest point between the rolls 1 and 2) by which a billet 7 is formed. An inert gas is blown from an inert gas supplying device 12 to a vessel 11 installed at the upper part of the tundish 4 to maintain an inert atmosphere in the vessel 11 and to apply pressure on the surface of the metal 3. When the pressure is applied on the surface of the metal 3 by the inert gas blown into the vessel, the pressure is applied on the inside surface side of the shells 9 and 10 as well as the solidified shells are brought into tight contact with the roll surfaces, by which the ruggedness of the solidified shells is decreased and a uniform thin plate is formed.
