Claim 12:
13. A stator vane comprising:
a platform defining an opening;
an airfoil having a leading edge, a trailing edge, a suction side wall, and a pressure side wall, the airfoil extending radially between a base and a tip, wherein at least one of the base or the tip includes a protrusion, the protrusion extending into the opening of the platform such that the platform surrounds the protrusion of the airfoil;
a braze joint disposed between and fixedly coupling the platform and the protrusion of the airfoil; and
a cooling circuit defined in the platform to cool the braze joint, wherein the cooling circuit comprises one or more inlet channels extending to a plenum and configured to direct coolant to impinge upon a joint boundary wall, wherein the joint
boundary wall contacts the braze joint and partially defines the plenum, and wherein each outlet channel of one or more outlet channels is fluidly coupled to the plenum and is offset from each inlet channel of the one or more inlet channels both radially and in a direction that extends along a perimeter of the protrusion.
