Description
цевое стекло, езапфир и другие неор . ганические диэлектрики. Сборку помеjmaTOT в печь с защитной или восстановйтельной средой и производ т термбобработку по режиму полного отжига используемой в качестве материала обоймы 1 марки стали.target glass, ozffir and other neor. dielectric dielectric. PomejmaTOT is assembled into a furnace with a protective or recuperative medium and thermal treatment is carried out according to the complete annealing mode of the first grade of steel used as the material of the sleeve.
Например, охватывающую деталь выполн ют из стали марки У-8, закаленной до твердости 60-62, нанос т слой меди толщиной 50 мкм, размокают в ней деталь из высокоглиноземистой керамики и нагревают узел до 750с и охлаждают со скоростью пор дка 6080 С/час .For example, the female part is made of U-8 steel hardened to a hardness of 60-62, a 50 μm thick layer of copper is applied, a high-alumina ceramic part is soaked in it and the node is heated to 750 s and cooled at a rate of about 6080 C / hour .
В процессе указайной термообработки происходит распад мартенситной структуры стали в структуру ферритоцементитного типа (FSg-tFe C), приIn the process of secret heat treatment, the martensitic structure of the steel decomposes into a ferritic-cementite type (FSg-tFe C), with
этом линейные размеры обоймы уменьшаютс . Это объ сн етс тем, что среди всех структурных составл ющих стали, образующихс при закалке и отпуске , мартенсит обладает наибольшим удельным объемом, а аустенит - наименьшим . Поэтому распадаустенита (закалка) вызывает расширение стали, а распад мартенсита на феррит и цементит (полный отжиг) - ее сжатие. Поэтому указанный процесс приводит к обжатию установленного в обойме диэлектрического диска через слой высокопластичного металла, при этом происходит образование герметичного соединени .In this way, the linear dimensions of the clip are reduced. This is due to the fact that among all the structural components of steel formed during quenching and tempering, martensite has the largest specific volume, and austenite - the smallest. Therefore, the decomposition of austenite (quenching) causes the expansion of steel, and the decomposition of martensite into ferrite and cementite (complete annealing) causes its compression. Therefore, this process leads to the compression of the dielectric disc mounted in the cage through a layer of highly ductile metal, thus forming a tight joint.
Способ характеризуетс простотой выполнени , не требует специальной технологической о:настки дл посадки и центрировани керамической детали и примен етс дл соединений материалов как с большими, так и с малыми значени гда разноотей в КТР леталла и диэлектрика, включа их нулевое и отрицательное значение.The method is characterized by simplicity of implementation, does not require special technological treatment: fittings for planting and centering the ceramic part and is used to connect materials with both large and small values, where there are differences in the CTE of lethal and dielectric, including their zero and negative values.
