Abstract (en)
[origin: EP2883972A1] [Object] To provide a titanium alloy material containing a platinum group metal, the titanium alloy material being able to sufficiently suppress corrosion accompanying surface roughening. [Solution] Provided is a titanium alloy material including a platinum group metal. When an average value of intensity of background signals in surface mapping analysis using an EPMA surface analysis apparatus is N and N+3N 1/2 is maximum intensity of the background signal of an Fe or S characteristic X-ray, an area ratio at which a signal of an Fe or S characteristic X-ray exceeding the maximum intensity is obtained is 0.1 % or less.
