Patent ID: 7575418

Claim:
A turbine component, comprising: a cast, wrought, or cast-and-wrought substrate; a diffusion-mitigating layer affixed to the substrate, wherein the diffusion-mitigating layer is selected from a group consisting of vanadium, niobium, hafnium, tantalum, zirconium, and a combination comprising at least one of the foregoing metals; and an erosion protective structure affixed to a surface of the diffusion-mitigating layer that is opposed to the surface in contact with the substrate, wherein the protective structure comprises an α-β titanium alloy, a near-β titanium alloy or a β-titanium alloy, wherein the α-β titanium alloy, the near-β titanium alloy or the β-titanium alloy each comprise a β phase that has a titanium rich body-center-cubic structure and belongs to Pearson symbol cl2 or space group Im 3 m; and wherein the protective structure forms the outer layer of the turbine component.
