Claim:
1. A component comprising: a substrate comprising an outer surface and an inner surface, wherein the inner surface defines at least one hollow, interior space, wherein the outer surface of the substrate defines a pressure side wall and a suction side wall, wherein the pressure and suction side walls are joined together at a leading edge and at a trailing edge of the component, wherein the outer surface defines one or more substantially axially oriented grooves, and wherein each groove is in fluid communication with a respective hollow, interior space; and a coating disposed over at least a portion of the outer surface of the substrate, wherein the coating comprises at least one structural coating, wherein the at least one structural coating extends over the one or more grooves, such that the one or more grooves and the structural coating together define one or more channels for cooling the trailing edge of the component, wherein at least one of the one or more channels comprises an inlet portion that extends partially along the suction side wall, an outlet portion that intersects the pressure side wall at the trailing edge and extending through the coating to define an outlet at the trailing edge, and an intermediate portion that extends between the inlet and outlet portions of the cooling channel.
