PROBLEM TO BE SOLVED: To provide titanium-containing articles having improved surface finishes and methods for changing the surface of titanium containing articles, for example, by removing overstock.SOLUTION: One example method includes passing a fluid at high pressure across a surface of an titanium aluminide alloy-containing article, for example, a turbine blade, at high linear speed and deforming the surface of the titanium aluminide alloy-containing article, and removing material from the surface of the titanium aluminide alloy-containing article. The invention can be used in fabricating high performance turbine blades. The methods disclosed can be applied to the treatment of any titanium-containing article for which it is difficult to obtain an improved surface finish. |
