摘要： The invention provides an axial flow machine that effectively reduces the unstable hydrodynamic force induced by leakage flow and thereby prevents unstable vibrations.
A steam turbine comprises: a ring-shaped cover 6 connected to the outer circumferential side of a rotor blade row 4; and a ring-shaped concave section 12 provided on an inner circumferential surface 8 of a casing 1 for housing the cover 6. A narrow passage 15 is formed between an outer circumferential surface 13 of the cover 6 and a bottom surface 14 of the concave section 12. A narrow inflow passage 18 is formed between an upstream lateral surface 16 of the cover 6 and an upstream lateral surface 17 of the concave section 12. A narrow outflow passage 21 is formed between a downstream lateral surface 19 of the cover 6 and a downstream lateral surface 20 of the concave section 12. Between the narrow inflow passage 18 and the narrow passage 15 lies an expanded inflow passage 22. The expanded inflow passage 22 has a substantially uniform structure in a circumferential direction and is formed such that it is located on the more outer circumferential side than the bottom surface 20 of the concave section 12 and such that it is located upstream side in terms of the rotor's axial direction with respect to the upstream lateral surface 17 of the concave section 12.

摘要： A multi-component braze filler alloy comprising 60-70% by weight CM247 superalloy and BRB braze alloy is diffusion brazed to a CM247 alloy base substrate, such as a gas turbine blade or vane. The substrate/braze interface may be subsequently weld-repaired without de-melting and migrating the braze alloy from the interface. The weld zone and surrounding area are solidification crack resistant. After the alloy composition is brazed to the base substrate the component may be returned to service. Thereafter the component remains repairable by welding or re-brazing, if needed to correct future in-service defects.
摘要翻译：将包含60-70重量％CM247超级合金和BRB铜焊合金的多组分钎焊合金扩散钎焊到CM247合金基底，例如燃气轮机叶片或叶片。随后可以对基底/铜焊界面进行焊接修复，而不会使铜焊合金从界面上解除熔化并迁移。焊接区和周围区域具有抗凝固裂纹。在将合金组合物钎焊到基底上之后，可以将部件返回使用。此后，如果需要纠正未来的使用中的缺陷，则可以通过焊接或重新钎焊维修组件。

摘要： The present invention relates to a method for the reconditioning of a cover plate (10) of a vane (1) of a turbomachine, in particular of a gas turbine, by means of a forming apparatus, a mounting portion with fastening elements (36, 37) being connected, from a vane root (34) of the vane (1), radially outwardly with respect to a rotary axis of the turbomachine, and an airfoil (30) being connected in the opposite direction. Further, a vane head (33) is connected to the airfoil (30) and the cover plate (10) is connected to the vane head (33), the cover plate (10) being bulged in the direction opposite to the vane root (34). In a first step, an analysis step, dimensions of the vane (1) in relation to the cover plate (10) are determined in respect of predefined reference points of the vane (1) by means of dimension analysis. If, after the analysis step, forming of the cover plate (10) seems necessary and possible on account of a comparison of measurement values from the analysis step with predefined dimension values, the bulged cover plate (10) is formed, in particular at least essentially pressed smooth, by pressing by means of the forming apparatus in a forming step. After the forming step, the cover plate (10) is preferably re-treated in one or more follow-up steps. The invention relates, further, to an apparatus for carrying out the method according to the invention.
