摘要： The invention provides (1) a titanium alloy with excellent corrosion resistance consisting essentially of 10-40 wt % of Mo, 0.1-15 wt % of Cr, and the balance of Ti and unavoidable impurities and (2) a titanium alloy according to (1) which further contains 0.01-2.0 wt % (in total) of Ru, Ir, Os, Pd, Pt, or/and Rh. The addition of Mo allows Ti-based alloys to form on the surface a protective film with a high concentration of Mo, whereby their corrosion resistance in non-oxidizing acids, such as hydrochloric and sulfuric acids, is markedly improved. In environments where oxidants are present, even but a few ppm in amount, Mo comes out in solution, seriously affecting the corrosion resistance of the alloys. To avoid this, Cr must also be added. The addition of Cr helps keep Mo from dissolving out and thereby prevent the deterioration of corrosion resistance by the action of oxidants in the environments. The platinum group elements, singly or in combination, further improve the corrosion resistance.

摘要翻译： 本发明提供（1）具有优异耐腐蚀性的钛合金，其基本上由Mo的10-40重量％，Cr的0.1-15重量％，余量的Ti和不可避免的杂质构成，（2）根据（ 1），其还含有Ru，Ir，Os，Pd，Pt或/和Rh的0.01-2.0重量％（总计）。 Mo的添加允许Ti基合金在表面上形成具有高浓度Mo的保护膜，由此其在非氧化性酸如盐酸和硫酸中的耐腐蚀性显着提高。 在存在氧化剂的环境中，即使是少量的ppm，Mo在溶液中出现，严重影响了合金的耐腐蚀性。 为了避免这种情况，还必须添加Cr。 添加Cr有助于使Mo不溶解，从而通过环境中的氧化剂的作用防止耐腐蚀性的劣化。 单独或组合的铂族元素进一步提高耐腐蚀性。

摘要： High quality titanium ingot is produced by using recovered titanium scrap as a raw material and adding additives. Scrap, each having individual information of identification and process profile information, is passed through automatic reading means to obtain the information and to store it in a data server. A calculating means calculates a combination of the scrap, titanium sponge and additives and feed rate of each of them so as to satisfy chemical composition and producing rate of a target ingot product using the individual identification pieces of information stored in the data server, during a beginning step of the ingot production, and transmits electrical signals corresponding to calculated results of the combination and the feed rates from the calculating means to a feed rate controlling means of each feed means of the titanium scrap, titanium sponge, and additives and then starting supply of them, and detecting means equipped at an extracting part of the ingot product reads actual producing rate of the ingot product, after the beginning step of the ingot production. The calculating means controls feed rate of the titanium scrap, titanium sponge, and/or additives based on the actual producing rate.
