摘要:
Turbine engine (80) components, such as blades (92), vanes (104, 106), ring segment 110 abradable surfaces 120, or transitions (85), have furcated engineered groove features (EGFs) (403, 404, 418, 509, 511, 512) that cut into the outer surface of the component's thermal barrier coating (TBC). In some embodiments, the EGF planform pattern defines adjoining outer hexagons (560, 640, 670, 690, 710). In some embodiments, the EGF pattern further defines within each outer hexagon (560, 640, 670, 690, 710) a planform pattern of adjoining inner polygons (570, 580, 590, 600, 610, 680, 682, 700, 702, 704, 705, 720). At least three respective groove segments (509, 511, 512) within the EGF pattern (506, 507, 508) converge at each respective outer hexagonal vertex (510, 564) or inner polygonal vertex (574, 564, 604, 614) in a multifurcated pattern, so that crack-inducing stresses are attenuated in cascading fashion, as the stress (σA) is furcated (σB, σC) at each successive vertex juncture.

The invention relates to a method for producing a capacitor. The invention further relates to a capacitor and to the use of a capacitor of said type for producing an electric cable, a coaxial cable and/or a resonant heating cable. The invention for the first time discloses a method suitable for mass production of a capacitor, in particular a cylindrical capacitor. In said method, a main member is alternately coated with dielectric and electrically conducting layers using thermal spraying and/or spraying and is then sintered. Compared to the prior art, the result is great design variability in terms of the capacitance and breakdown voltage as well as great temperature resistance.
