Turbine nozzles and methods of manufacturing the same

A method of manufacturing a turbine nozzle, the method comprising the steps of:

• imparting an oxide layer onto a surface of a first end of a vane;
• inserting the first end of the vane into a first opening in a first ring forming a first joint and inserting a second end of the vane into a second opening in a second ring forming a second joint;
• applying a first braze material to the first joint;
• applying a second braze material to the second joint;
• and
• transforming the first braze material at the first joint into a slip joint and the second braze material at the second joint into a bonded joint to form the turbine nozzle.
