| 摘要 |
The present invention relates to a method for manufacturing a turbine assembly (10, 10a), which comprises at least two aerofoils (12, 14) that are arranged adjacent towards each other and are embodied as a twin vane segment (40, 40a). To provide a proper and reliable protection the method comprises at least the following steps:
- processing the turbine assembly (10, 10a) with a first protection technique that provides a first protection for the at least two adjacent aerofoils (12, 14), wherein at least one region (16) of one aerofoil (14) of the at least two adjacent aerofoils (12, 14) remains unprocessed,
- pre-processing of the at least one region (16) of the one aerofoil (14) of the at least two adjacent aerofoils (12, 14) that will remain unprocessed by the processing with the first protection technique or post-processing of the at least one region (16) of the one aerofoil (14) of the at least two adjacent aerofoils (12, 14) that remained unprocessed by the processing with the first protection technique with a second protection technique that provides a second protection for the at least one region (16) of the one aerofoil (14) of the at least two adjacent aerofoils (12, 14) that will remain unprocessed or that remained unprocessed, wherein the first and the second protection techniques differ from one another. |
