Description

Пример 2. На экспериментальный образец и образец-свидетель из УУКМ методом газофазного осаждени  был нанесен слой карбида тантала толщиной 10-12 мкм. Затем из шликерной суспензии, содержащей смесь порошков WSi2, WsSia, HfSi2 эвтектического состава, нанесли покрытие толщиной 70-100 мкм. После высокотемпературного оплавлени  покрыти  в печи типа СНВ при 1950°С (Рост. 104 мм рт.ст.)образец вместе с образцом-свидетелем подвергали активированному силицированию в вакуумной печи типа СШВ взасыпке порошка кремни  при 1200°С в течение 8 ч. Контрольный рентгенофазный анализ покрыти  на образце-свидетеле показал присутствие в многослойном покрытии промежуточной фазы силицидов тантала.EXAMPLE 2 A tantalum carbide layer 10-12 µm thick was deposited by a gas-phase deposition method on a test sample and a test sample from CCCM. Then, from a slip slurry containing a mixture of eutectic powders WSi2, WsSia, HfSi2, a coating thickness of 70-100 μm was applied. After high-temperature melting of the coating in the START furnace at 1950 ° C (Rost. 104 mmHg), the sample together with the witness sample was subjected to activated silicification in a vacuum furnace of the СШВ type by spraying silicon powder at 1200 ° С for 8 h. Control X-ray phase analysis of the coating on the witness sample showed the presence of tantalum silicides in the multilayer coating of the intermediate phase.

Образец с покрытием подвергали испытанию в окислительном потоке газа при 1900°С в течение 1,5 ч. После каждой ос - тиминутной выдержки при 1900°С изделиеThe coated sample was tested in an oxidizing gas stream at 1900 ° C for 1.5 hours. After each otminute exposure at 1900 ° C, the product

охлаждали до 100°С и вновь нагревали до 1900°С. Спуст  15 термоциклов покрытие осталось без изменений, потер  массы практически отсутствовала.cooled to 100 ° C and again heated to 1900 ° C. After 15 thermal cycles, the coating remained unchanged, there was practically no mass loss.

Использование предлагаемого способаUsing the proposed method

нанесени  покрыти  на издели  из УУКМ позвол ет по сравнению с техническим решением , описанным в прототипе, резко подн ть работоспособность изделий из УУКМ в окислительной среде при температурах доcoating on products from UCM allows, in comparison with the technical solution described in the prototype, to dramatically increase the performance of products from UCM in an oxidizing environment at temperatures up to
