摘要： PROBLEM TO BE SOLVED: To provide a moving vane member excellent in durability, and to provide a manufacturing method of the moving vane member. SOLUTION: An impeller 21 in which residual tensile stress remains is rotated at a speed higher than that in conventional use, so that a high stress generating part 24 inside the impeller 21 is plastically deformed by centrifugal force F. Thus, after the rotation stops, residual compressive stress remains in the high stress generating part 24 and the residual tensile stress is removed. Therefore, repeated tensile stress applied to the high stress generating part 24 can be reduced, resulting in providing the more durable impeller 21. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To perform a friction-stirring treatment and a burr-removal work by using the same machine tool, to restrain variation of treated depth caused by thermal expansion of a rotary tool and to thereby prevent non-filling defect. SOLUTION: A machine tool 100 with a tool changer 101 is used. The tool changer 101 holds at least two rotary tools 4 each having the same shape and at least one burr-removal tool T. After treatment with the burr-removal tool T, the rotary tool 4 other than the tool 4 used just before is selected to alternately perform surface treatment and removal work of burrs caused by the surface treatment.

摘要： PROBLEM TO BE SOLVED: To provide a heat shielding coating series for parts used under a severe thermal environment, such as turbine, combustor and augmenter of a gas turbine engine. SOLUTION: A heat shielding coating series 20 is constituted by forming a heat shielding ceramic layer 26 on a bonding coat 24 of nickel aluminide alloy. The nickel aluminide bonding coat 24 is mainly composed of β-NiAl phase and contains zirconium. It is preferable to form the bonding coat 24 by physical vapor deposition, such as magnetron sputtering, electron beam physical vapor deposition, jet vapor deposition, and plasma thermal spraying. The NiAl bonding coat 24 to which 0.05-0.5 atomic % zirconium is added exhibits greatly improved thermal fatigue life as compared with the conventional bond coat, and zirconium content of the order of 0.1 atomic % gives the best result.

摘要： PURPOSE:To correct the faces of teeth while preventing damages to carburized and hardened layers when the faces of teeth having carburized and hardened layers are corrected. CONSTITUTION:The carburized and hardened layers 20 are formed on the surface of a toothed steel alloy member. The ironing allowance of tooth 15 is about 0.1 to 0.3mm in terms of BBD dimension. Correcting is carried out by holding the surface of teeth 15 by pressing to be ironed by the ironing surface 36 of a mandrel 31 while the outer circumference 1c of toothed member is contained by the first containing surface 35 of a die 30. The base material part inside of carburized and hardened layer 20 of tooth part 12 is allowed to flow in the direction shown by the arrow K1 to fill a clearance 40. Since material moving a accompanying ironing absorbed by clearances 40 and 44, a flow along the axial longitudinal direction is not basically generated.

摘要： PURPOSE:To draw fine and clear patterns on the surface of a noble metal ring by making a pressure processing to a matte finished part which involves slippage with a cutter tip having a specified high hardness and a roundness of minute diameter, and thereby generating luster patterns. CONSTITUTION:A processing rod 13 is fitted at the foremost with a cutter tip 14, presses therewith a matte finished surface 3 of the body 1 of a noble metal ring, and destroys by pressure the fine surface unevenness so that a smooth surface 2 is generated. On the surface of the ring body 1, any desired patterns due to this smooth surface 2 are drawn by driving the drive parts 12A, 13A of a three-axis carving machine T. The drive parts 12A, 13A of the machine T are operated according to the processing procedures programmed in advance in conformity to the command from an NC device 100, and the specified patterns are drawn automatically on the surface of the ring body 1. Therein the representation of a surface is given as overlapping of lines, where the feed of the drive part 12A is made precisely by micro-feeding, so that surface patterns free from unevenness are produced.
