    • A titanium alloy including by mass %, a platinum group metal: 0.01 to 0.15% and a rare earth metal: 0.001 to 0.10%, with the balance being Ti and impurities. The titanium alloy preferably includes as a partial replacement for Ti, Co: 0.05 to 1.00% by mass, and the content of the platinum group metal is preferably in the range of 0.01 to 0.05% by mass. Furthermore, it is preferred that the platinum group metal be Pd and the rare earth metal be Y. Consequently, it is possible to provide a titanium alloy having corrosion resistance comparable to or better than that of the conventional art as well as good workability while offering an economic advantage with a lower content of platinum group metal or an advantage of less likelihood of corrosion growth originating at defects such as flaws that occurred in the surface.
    • 含有质量%的钛合金,铂族金属:0.01〜0.15%,稀土金属:0.001〜0.10%,余量为Ti和杂质。 钛合金优选包含Ti,Co的部分替代物:0.05〜1.00质量%,铂族金属的含量优选为0.01〜0.05质量%。 此外,优选铂族金属为Pd,稀土金属为Y.因此,可以提供具有与常规技术相当或优于其耐腐蚀性的钛合金以及良好的可加工性,同时提供 具有较低含量的铂族金属的经济优势或由表面上发生的缺陷等缺陷引起的腐蚀增长可能性较小的优点。
