Description
Кроме того, одновременно увеличивает с диффузионна подвижность атомов хрома в поверхностном схпое.In addition, it simultaneously increases the diffusion mobility of chromium atoms in the surface surface.
При использовании стружки магни размером более 1000 мкм образующа с поверхность недостаточно развита. Необходимое раскисление и активирование смеси не обеспечиваетс и проведение процесса при более низкой температуре невозможно.When using magnesium chips larger than 1000 microns, the surface forming is insufficiently developed. The necessary deoxidation and activation of the mixture is not ensured and the process cannot be carried out at a lower temperature.
При введении стружки размером менее 200 мкм возможно самовозгорание смеси при выгрузке гор чего контей ера ,.When chips of less than 200 microns are introduced, the mixture may self-ignite when unloading a hot container,.
Образующийс диффузионный слой, представл ющий собой твердый растворThe resulting diffusion layer is a solid solution.
хрома в d -железе, в зкий, пластичный , не содержит трещин, сколов Низка температура процесса, небольша продолжительность (0,5-1,5 ч) предотвращает выделение карбонитридной фазы по границам аустенитного зерна.chromium in d-iron, viscous, plastic, does not contain cracks, chips. Low process temperature, short duration (0.5-1.5 h) prevents the carbonitride phase from separating along the austenitic grain boundaries.
Варианты предлагаемого состава представлены в табл. 1.Variants of the proposed composition are presented in table. one.
Режим насыщени и результаты исследовани приведены в табл. 2 Как видно из таблицы,врем обрабоки сократилось в 10 раз, а получае влй хромированный слой вл етс боле гюастичным, не имеет трещин, сколов f не содержит ( -фазу,The saturation regime and the results of the study are shown in Table. 2 As can be seen from the table, the processing time has been reduced by 10 times, and the resulting chrome layer is more than just a little, has no cracks, does not contain any chipping f ((phase,
