Claim Text:
1. A stator vane for a turbine engine used to produce electrical power, the stator vane comprising: an airfoil with an external surface exposed to a hot gas flow passing through a turbine; a liner forming a liquid metal coolant passage within the airfoil to provide cooling for the airfoil; the airfoil formed from a base metal that is reactive to a liquid metal coolant; a gap formed between the airfoil and the liner; the gap filled with a heat conducting liquid to transfer heat from the airfoil to the liquid metal coolant through the liner; and, the liner being formed from a material that is non-reactive to both the base metal of the airfoil and the liquid metal coolant.
