Abstract
A method of joining first and second turbine vanes is provided. The method includes casting and machining each of the first and second turbine vanes, coating each of the first and second turbine vanes with thermal barrier coating (TBC) and executing field assisted sintering technology (FAST) processing to join the first and second turbine vanes.
Claims20
A method of joining first and second turbine vanes, the method comprising:
- casting and machining each of the first and second turbine vanes;
- coating each of the first and second turbine vanes with thermal barrier coating (TBC);
- and
- executing field assisted sintering technology (FAST) processing to join the first and second turbine vanes.

A method of joining first and second turbine vane singlets, the method comprising:
- casting and machining each of the first and second turbine vane singlets;
- coating each of the first and second turbine vane singlets with thermal barrier coating (TBC);
- and
- executing field assisted sintering technology (FAST) processing to join the first and second turbine vane singlets to form a turbine vane doublet.
1 more element
An assembly of at least turbine vane singlets, comprising:
- first and second turbine vane singlets,
- each of the first and second turbine vane singlets being separately coated with a thermal barrier coating,
- each of the first and second turbine vane singlets comprising an inner platform, an outer platform and an airfoil section radially interposed between the inner and outer platforms, and
- the first and second turbine vane singlets being joined by field assisted sintering technology (FAST) processing along a bond line at one or more of the respective inner platforms and the respective outer platforms to form a turbine vane doublet.
