Near Net Shape Turbine Blade Repair Using a Joining and Coating Hybrid Process (B01)

在前两个资助期开发的混合工艺将进一步开发，考虑到整个喷气发动机系统的功能。这一过程的再现性也将被调查，从而产生的过程可靠性。此外，热障涂层（TBC）将在第三个资助期集成到这种混合技术中。由于在第二个资助期中显示，通过热喷涂成功地进行了铝浸渍，因此在保护气炉中将涂层系统填料-金属/麦克雷利/铝/TBC的普通热处理（钎焊和镀铝）作为连续过程进行似乎是一致的。

The hybrid process which was developed in the first two funding periods will be developed further, with regards to the functionality of the overall jet engine system. This reproducibility of this process will also be investigated, and thus the resulting process reliability. Furthermore, the thermal barrier coating (TBC) will be integrated in this hybrid technology in the third funding period. Since it was shown in the second funding period that the aluminium impregnation was performed successfully by thermal spraying, it seems to be consistent to carry out the common heat treatment (brazing and aluminising) of the coating system filler-metal/MCrAlY/Al/TBC as a continuous process in a shielding gas furnace.
