<p>A gas turbine engine turbine blade (10) and method for making the same comprising an airfoil section (12), a platform section (14), an under platform section (16), and a dovetail section (18) having an exterior surface (32), the exterior surface of the dovetail section comprising a shank (26) and a serrated exterior (28). The blade (10) further comprises a silicon-modified diffusion aluminide layer a surface of a turbine blade section selected from the group consisting of the exterior surface of the under platform section (32), the exterior surface of the dovetail section (26), and combinations thereof, the silicon modified diffusion aluminide layer having a concentration of silicon at a surface of the silicon-modified diffusion aluminide layer in the range of about 1 weight percent to about 10 weight percent and a concentration of aluminum at the surface of the silicon modified diffusion aluminide layer in the range of about 5 weight percent to about 25 weight percent.</p> |
