Method for detecting surface oxidation on titanium aluminide metallic material |
摘要 |
The present invention is a method of determining oxidation on a titanium aluminide material. An aqueous saturated solution of oxalic acid is prepared. The saturated solution of oxalic acid is combined with a minor portion of hydrofluoric acid solution. The resultant oxalic acid/hydrofluoric acid solution is mixed. The titanium aluminide material is immersed in the mixed solution for a sufficiently long period to allow exposure of the oxidized surface followed by inspection thereof for a white layer indicating the presence of oxidation on its surface.
