摘要： A manufacturing method is provided. During this method, a preform component is provided for a turbine engine. The preform component includes a substrate. A preform meter section and a preform diffuser section are formed in the substrate. An internal coating is applied to at least the preform meter section to provide a meter section of a cooling aperture. External coating material is applied over the substrate. The applying of the external coating material forms an external coating over the substrate. The applying of the external coating also builds up the external coating material within the preform diffuser section to form a diffuser section of the cooling aperture.

摘要： A double-jet film cooling structure includes: an injection port, formed on a wall surface facing a high-temperature gas passage; a main passage as a straight round hole to supply cooling medium to the injection port; a pair of branch passages as straight round holes; and communication passages connecting the main passage to the branch passages. The main passage and the branch passages have same constant inner diameters. Each communication passages has an envelope surface obtained by continuously arranging straight round holes each passing a branch point and having the constant inner diameter. Transverse injection angles of the branch passages relative to gas flow along the wall surface are oriented in opposite directions. An angle between axial direction of the main passage and the wall surface is greater than an angle formed between axial direction of branch passage and the wall surface.

摘要： The present invention is an electrochemical machining tool equipped with a tool body that comprises: an electrode that extends along an axial line and inside which a flow channel through which an electrolytic solution flows towards the tip end is formed; an insulating layer covering the outer circumferential surface of the electrode so as to expose the tip end face of the electrode; and a flow channel-partitioning part for partitioning the flow channel into a first flow channel containing the axial line and a second flow channel positioned on the outer circumferential side of the first flow channel. The electrochemical machining tool has a configuration in which a fluid outflow section for directing electrolytic solution, which is flowing through the second flow channel, outward in the radial direction of the tool body is formed on a portion of the circumference of the tool body.
