摘要： PROBLEM TO BE SOLVED: To obtain a heat-insulating coating material which can prevent peeling in high-temperature use and exhibits a high heat-insulating effect; and to provide a turbine member and a gas turbine both coated with the coating material. SOLUTION: The heat-insulating coating material includes a ceramic layer 23 which is formed on a heat-resistant alloy base material 21 for high- temperature use in order to elevate the heat resistance of the base material 21. The ceramic layer 23 is formed via a bond coat layer 22 formed as a metal bonding layer and comprises ZrO2 containing Er2 O3 added as a stabilizer. The turbine member and gas turbine are surface-coated with the heat-insulating material.

摘要： PURPOSE: To endure against severe using conditions by forming of iron-aluminum binary alloy in which iron is a main ingredient and specific atomic % of aluminum is added thereto as a base material. CONSTITUTION: An Fe-Al binary alloy in which iron is a main ingredient and 34 to 48 atomic % (20 to 32wt.%) of aluminum is added thereto is used as a base material. For example, the alloy containing Fe, 24.4wt.% of Al and 0.024wt.% of B is used as the base material, manufactured in the shape completely covering a heat transfer tube 1 by a precise casting method, and mounted at the tube 1 by a bolt 3 after a boiler is assembled. An Al2 O3 is formed as an oxide film on the surface of a protective member 2 by the selective oxidation of the Al included in the base material. Since the material is a B2 type intermetallic compound single phase, the Al2 O3 is stably formed for a long time. Accordingly, the tube 1 can be completely protected even under the working conditions in which oxidation, corrosion and wear are apt to occur to prevent its thinning.

摘要： PURPOSE:To produce a sound casting free from hexagonal cracking by casting a molten FeAl intermetallic compound, where Fe and Al are blended at specific ratio, in a mold and performing cooling at specific solidification cooling velocity. CONSTITUTION:A molten FeAl intermetallic compound having a composition consisting of, by atomic concentration, 37-53% Al and the balance Fe is cast in a graphite mold, by which a casting of Feel intermetallic compound is prepared. At this time, a fibrous ceramic wool is stuck on the graphite mold to change the degree of heat radiation and the molten metal is cast in a state preheated to about 500 deg.C, and cooling is done while controlling solidification cooling velocity to 1000 deg.C/hr. By this method, the occurrence of hexagonal crack in the grain boundaries of a product can be prevented, and the superior casting as oxidation-resisting, corrosion-resisting, and wear-resistant parts can be obtained.

摘要： PURPOSE:To produce a reinforcing type alloy in which oxides particles are uniformly dispersed in a metal in a large quantity and in a short time by uniformly dispersing the oxide in a molten metal stream to form metal wires, pulverizing and sintering the wires by a hot extrusion. CONSTITUTION:The molten metal 1 (Ni base alloy, etc.) at about 1500 deg.C is poured from a tundish 2 and an inert gas 5 and oxide particles 6 (Al2O3, etc.) with about 2mm to 0.1mu particle size are blown on a molten metal stream 3 from a nozzle 4 to be uniformly dispersed (about 0.5 to 2% volumetric ratio). The molten metal 7 is introduced into a water-cooled bowl-shaped vessel 8 made of copper rotating at about 600rpm to form metal wires or metal ribbons 9, pulverized in an inert gas by using a ball mill to form metal powders 10 dispersed with oxide and is then vacuum-encapsulated in a tube 12 made of a mild steel. Then, metal powders with the tube 12 are heated to about 1100 deg.C and sintered by extrusion with a hot extruding machine to obtain the oxide dispersion reinforcing type alloy 13.

摘要： PURPOSE:To improve erosion resistance of a turbine blade by welding a metal segment which is composed of an age-hardening type titanium alloy to a partially manufactured turbine blade and performing closed die forging, in the case of manufacturing the turbine blade made of a titanium alloy by means of forging. CONSTITUTION:In the case of manufacturing a turbine blade made of a titanium alloy by means of closed die forging, a bevel forming process is performed to a part 2 which faces a steam inlet side on the stage of the partially manufactured product of said blade. Next, a metal segment 3 which is composed of an age-hardening type titanium alloy is attached to said part 2. A thermal sprayed part 5 is secured by radiating an electron beam 4 along the surface of the partially manufactured product 1 joined to the metal segment 3. Then, the partially manufactured product 1, to which the metal segment 3 is welded, is inserted into a heating furnace and heated entirely at the temperature of approximately 950 deg.C, then subjected to hot and closed die forging. Thereby a specifically shaped turbine blade, which has a strong clad layer 3a made of an age-hardening type titanium alloy on its steam inlet side, is secured.
