Description
р чему обеспечиваетс взаимна диффузи тугоилавких и разнородных материалов, труднорастворимых друг в друге, снижаетс температура процесса, что позвол ет получать соединени без интерметаллидных прослоек. Величиной нарушенного сло и характером образующихс в нем дефектов можно легко управл ть, измен энергию и длительность импульса тока, а также крутизну переднего фронта импульса.the result is a mutual diffusion of low melting and dissimilar materials that are difficult to dissolve in each other, the process temperature is reduced, which allows to obtain compounds without intermetallic interlayers. The magnitude of the broken layer and the nature of the defects formed in it can be easily controlled by changing the energy and duration of the current pulse, as well as the steepness of the leading edge of the pulse.
Пример конкретного исполнени . Свариваемые поверхности ниоби и стали X18HIOT электроэрозионно обрабатывают на установке А 207-40 с энергией импульса 200 млдж и длительностью 5-10 сек. После этого свариваемые детали устанавливают в вакуумную камеру диффузионной установки, создают разрежение 2-10 тор, затем детали нагревают до 900°С и сдавливают в течение 5 мин сварочным давлением 1 кгc/cм. После образовани соединени сваренные детали охлаждают под давлением до 20-40°С и извлекают из камеры.An example of a specific implementation. The welded surfaces of niobium and steel X18HIOT are electroerosively processed at unit A 207-40 with a pulse energy of 200 mlj and a duration of 5-10 seconds. After that, the parts to be welded are installed in the vacuum chamber of the diffusion unit, a vacuum of 2-10 torr is created, then the parts are heated to 900 ° C and squeezed for 5 minutes with a welding pressure of 1 kgc / cm. After formation of the joint, the welded parts are cooled under pressure to 20-40 ° C and removed from the chamber.
Полученное соединение оказываетс равнопрочным стали Х18Н10Т. Интерметаллиды отсутствуют.The resulting compound is equal strength steel X18H10T. Intermetallic compounds are absent.
Реализаци изобретени позволит повысить качество соединени и снизить температуру процесса при сварке тугоплавких и разнородных металлов.The implementation of the invention will improve the quality of the connection and reduce the temperature of the process when welding refractory and dissimilar metals.
