Синтез ресурсных жаростойких эмалевых покрытий на основе стёкол барийалюмосиликатной системы для никелевых сплавов

Синтез ресурсных жаростойких эмалевых покрытий на основе стёкол барийалюмосиликатной системы для никелевых сплавов

Abstract

Изучена эффективность защитного действия ресурсных жаростойких покрытий на основе стёкол системы BaO-Al 2O 3-SiO 2 для защиты жаропрочных никелевых сплавов от высокотемпературной газовой коррозии. Исследована жаростойкость сплава с покрытием при температуре 1200 оС. При исследовании жаростойкости сплава с покрытием показано снижение окисляемости при температуре 1200 оС примерно в 4 раза, что позволяет исключить обезлегирование сплава. Исследована микроструктура сплава после термообработки с покрытием и без покрытия.

The efficiency of the protective action of heat-resistant coatings based on glasses in system BaO-Al 2O 3-SiO 2 for protection of heat-resistant nickel alloys from gas corrosion influence is studied. The oxidation level decrease for about 4 times was achieved, so the alloying elements lose may be neutralized. Microstructure of alloy after heat treatment with coating and without coating was studied.
