Beschreibung
Zusammenfassung:	One embodiment of the present invention discloses a method for forming an environmental barrier layer, which comprises: a coated layer forming step of coating a composition for forming the environmental barrier layer including silicate powder on a base material; and a post-treatment step of forming the environmental barrier layer by post-treating the coated layer. In the post-treatment step, a heating step of heating the coated layer to 1350 to 1500°C and a cooling step of cooling to a room temperature are repeated 3000 to 5000 times. Embodiments of the present invention provide the method for forming the environmental barrier layer capable of blocking permeation of external moisture or oxygen. 본 발명의 일 실시예는, 모재 상에 실리케이트 파우더를 포함하는 내환경 배리어층 형성용 조성물을 코팅하여 코팅층을 형성하는 단계; 및 상기 코팅층을 후처리 하여 상기 내환경 배리어층을 형성하는 후처리 단계;를 포함하고, 상기 후처리 단계는, 상기 코팅층을 1350℃ 내지 1500℃까지 가열하는 가열 단계와 실온까지 냉각시키는 냉각 단계를 3000회 내지 5000회 반복하는 내환경 배리어층의 형성 방법을 개시한다.
