Description

Изобретение относитс  к области обработки титановых сплавов с целью удалени  водорода с деталей и полуфабрикатов, прошедших травление. Известен способ обработки титановых сплавов в растворе плавиковой и азотной кислот. Предложенный способ отличаетс  от известного количественным соотношением компонентов раствора, содержаш,его другие концентрации плавиковой и азотной кислот, что удал ет наводороженный слой металла с поверхности титановых сплавов, прошедших травление. Способ осуществл ют следующим образом. После травлени  производ т обработку титановых сплавов в растворе следующего состава , вес. ,%: Азотна  кислота (уд. вес. 1,4) 62-83 Плавикова  кислота (уд. вес. 1,13)16-17 ВодаОстальное. Обработку ведут ори комнатной температуре 3-10 мин. Затем быстро и тщательно промывают холодной водой и сушат при 70- 100°С в течение 40-50 мин. В таблице приведены результаты спектраль (|ого анализа (без. зачистки поверхности) по содержанию водорода на поверхности титановых образцов после обработки В растворе по .предложенному способу. Предмет изобретени  Способ обработки поверхности титановых сплавов в растворе плавиковой и азотной кислот , отличающийс  тем, что, с целью удалени  наводороженного сло  с поверхности, компоненты вз ты в следующих соотношени х, вес. %: Азотна  кислота (уд. вес. 1,4) 62-83 Плавикова  кислота ( уд. вес. 1,13)16-17 ВодаОстальное, и процесс ведут при комнатной температуре течение 3-Ю мин. ,This invention relates to the treatment of titanium alloys in order to remove hydrogen from parts and semi-finished products that have been etched. There is a method of processing titanium alloys in a solution of hydrofluoric and nitric acids. The proposed method differs from the known proportion of the components of the solution containing its other concentrations of hydrofluoric and nitric acids, which removes the hydrogenated metal layer from the surface of titanium alloys that have been etched. The method is carried out as follows. After etching, titanium alloys are processed in a solution of the following composition, wt. ,%: Nitric acid (sp. Weight. 1.4) 62-83 Hydrofluoric acid (sp. Weight 1.13) 16-17 Water Remaining. The treatment is carried out at room temperature for 3-10 min. Then it is quickly and thoroughly washed with cold water and dried at 70-100 ° C for 40-50 minutes. The table shows the spectral results (| th analysis (without surface stripping) of the hydrogen content on the surface of titanium samples after processing the solution according to the proposed method. Subject of the invention in order to remove the hydrogenated layer from the surface, the components are taken in the following ratios, wt.%: Nitric acid (unit weight. 1.4) 62-83 Hydrofluoric acid (unit weight. 1.13) 16-17 Water Remaining, and the process is conducted at room temperature. eture for 3 minutes
