The identification method of titanium alloy, which is usually used in chemical analysis and spectroscopic analysis, is a method for accurate identification. But this is a laboratory method requesting for special equipment and technology. So it is important to determine a method that is easy and quick to identify in the waste site.
To this end, all kinds of methods are used to study in the field. Finally, it is found that the highly characteristic coloring oxide film is made of various kinds of titanium alloys. Using this highly characteristic coloring oxide film, it is easy to identify all kinds of titanium alloy. At the same time, by various conditional experiment, the results show that the method is feasible, and the effect is best by heating to 800 degrees for ten minutes. When it is in 800 degrees, all kinds of the titanium alloys can generate the highly characteristic coloring oxide film, which can easily be identified by each other.
