    Abstract: There is provided a surface treatment method for improving high temperature resistance oxidizability of a Ti—Al alloy in a manner suitable for mass production and the Ti—Al alloy. A Ti—Al alloy base material containing 15 at % or more to 55 at % or less of Al is heated and held in a gas atmosphere containing a fluorine source gas to form a fluorine inspissation layer with a thickness of 0.1 μm or more to 10 μm or less on the surface of the Ti—Al alloy base material, and a maximum concentration of F in the fluorine inspissation layer is made to be 2 at % or more to 35 at % or less. Thereby, when exposed to a high temperature oxidizing atmosphere, the surface of the Ti—Al alloy base is coated with an Al2O3 coating film having extremely low oxygen permeability. The alloy hence has excellent insusceptibility to high temperature oxidation. Thus, the poor insusceptibility to high temperature oxidation, which is a most serious disadvantage of the Ti—Al alloy which is lightweight and has high temperature strength, can be improved in a manner suitable for mass production. Therefore, the alloy can be used suitably for a supercharger turbine wheel, an engine valve, turbine blades for a gas turbine or the like, for example.

    Abstract: In an alloy based on titanium aluminides, metal droplets are obtained from a titanium aluminide metal melt. The metal droplets are enriched with halogens resulting in halogen-enriched titanium aluminide metal droplets. The alloy is molded from the halogen-enriched titanium aluminide metal droplets by, preferably hot isostatic, pressing. Titanium aluminide powder can be heated in a container, for a predetermined period of time, wherein an atmosphere, enriched with halogens, is or will be provided in the container, so that a halogen-enriched titanium aluminide metal powder is formed, or metal droplets are formed from a titanium aluminide metal melt. The metal droplets are enriched with halogens so that halogen-enriched titanium aluminide metal droplets result. Subsequently, the alloy is molded from the halogen-enriched titanium aluminide metal droplets.
