Thermal barrier coating system for a turbine airfoil usable in a turbine engine

摘要

A turbine airfoil usable in a turbine engine and having at least one cooling system with at least a portion of the cooling system positioned in internal aspects of the airfoil. The airfoil may also include a thermal barrier coating attachment system for attaching a thermal barrier coating to the airfoil. In one embodiment, the thermal barrier coating may be formed from one or more grooves in an outer surface of the outer wall forming the turbine airfoil. The grooves may have different cross-sectional shapes to enhance attachment of the thermal barrier coating to the airfoil.
