在表面内具有倾斜延伸的凹槽的部件及运行涡轮机的方法
Abstract:
本发明提出一种用于流体机械的部件，所述部件由基底和设在所述基底上的层构成，并且所述部件沿流动方向被溢流，并且所述部件具有外表面，在所述外表面中设有多个具有底部的、未完全延伸穿过所述部件的壁体的凹槽，并且所述凹槽仅设在所述基底上的层内，其中，所述部件的凹槽具有纵向方向，所述纵向方向从凹槽的底部起在凹槽的内部延伸直至所述表面，所述纵向方向相对于所述表面以一个角度α延伸，所述纵向方向与所述外表面形成一个角度α＜85°或者角度α＞95 °。
Abstract(English):

The invention provides a component for fluid machinery, which comprises a base and a layer arranged on the base. The component is overflowed along the flow direction and is provided with an outer surface. A plurality of bottomed slots, which incompletely extend and pass through the wall body of the component, are arranged on the outer surface. The slots are only arranged within the layer on the base. The slots of the component are in a longitudinal direction and the longitudinal direction extends from the bottoms of the slots into the interiors of the slot and till the surface of the component. Relative to the surface of the component, the longitudinal direction extends at an angle alpha. The angle alpha formed between the longitudinal direction and the outer surface of the component is smaller than 85 DEG C or greater than 95 DEG C.
