Abstract
Official abstract text for this publication.
An exhaust-gas turbocharger component ( 10 ) having at least one flow-conducting component surface ( 11 ) and having a discontinuity structure ( 12 ) which is formed on the component surface ( 11 ). The discontinuity structure ( 12 ) has a multiplicity of punctiform depressions ( 13 ) which are arranged separately from one another on at least one part of the component surface ( 11 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. An exhaust-gas turbocharger component ( 10 ) with at least one flow-conducting component surface ( 11 ) and a discontinuity structure ( 12 ) which is formed on the component surface ( 11 ), wherein the discontinuity structure ( 12 ) has a multiplicity of punctiform depressions ( 13 ) which are arranged separately from one another on at least one part of the component surface ( 11 ), wherein the punctiform depressions ( 13 ) are formed as a macrostructure in the range of tenths of a millimeter. 2. The exhaust-gas turbocharger component as claimed in claim 1 , wherein the depressions ( 13 ) have different shapes. 3. The exhaust-gas turbocharger component as claimed in claim 2 , wherein the depressions ( 13 ) are round, elliptical or polygonal. 4. The exhaust-gas turbocharger component as claimed in claim 1 , wherein the depressions ( 13 ) are arranged on all the flow-conducting components ( 10 ) of an exhaust-gas turbocharger ( 1 ). 5. The exhaust-gas turbocharger component as claimed in claim 1 , wherein the depressions are manufactured by casting. 6. An exhaust-gas turbocharger ( 1 ) having at least one exhaust-gas turbocharger component ( 10 ) which is provided with at least one flow-conducting component surface ( 11 ) and which has a discontinuity structure ( 12 ) formed on the component surface ( 11 ), wherein the discontinuity structure ( 12 ) has a multiplicity of punctiform depressions ( 13 ) which are arranged separately from one another on at least one part of the component surface ( 11 ), wherein the punctiform depressions ( 13 ) are formed as a macrostructure in the range of tenths of a millimeter. 7. The exhaust-gas turbocharger as claimed in claim 6 , wherein the depressions ( 13 ) have different shapes. 8. The exhaust-gas turbocharger as claimed in claim 7 , wherein the depressions ( 13 ) are round, elliptical or polygonal. 9. The exhaust-gas turbocharger as claimed in claim 6 , wherein the depressions ( 13 ) are arranged on all the flow-conducting components ( 10 ) of an exhaust-gas turbocharger ( 1 ). 10. The exhaust-gas turbocharger as claimed in claim 6 , wherein the depressions are manufactured by casting. 11. The exhaust-gas turbocharger as claimed in claim 6 , wherein the discontinuity structure ( 12 ) is formed as a macrostructure in the range of tenths of a millimeter. 12. An exhaust-gas turbocharger component ( 10 ) with at least one flow-conducting component surface ( 11 ) having a discontinuity structure ( 12 ) on at least one part of the component surface ( 11 ), the discontinuity structure ( 12 ) comprising a multiplicity of round, elliptical or polygonal depressions ( 13 ) arranged separately from one another, the depressions ( 13 ) in the range of tenths of a millimeter.
