ENVIRONMENTAL BARRIER COATING AND METHODS OF FORMING THE SAME
PROBLEM TO BE SOLVED: To provide methods of forming an environmental barrier coating (20).SOLUTION: A method includes disposing a powder-based coating on a substrate (12), heat-treating the powder-based coating at a temperature greater than 800°C and less than 1200°C to form a porous coating that includes surface-connected pores, infiltrating at least some of the surface-connected pores of the porous coating with an infiltrant material to form an infiltrated coating, and sintering the infiltrated coating at a temperature greater than 1200°C and less than 1500°C to form an environmental barrier coating (20) on the substrate (12).SELECTED DRAWING: Figure 2
【課題】耐環境コーティング（２０）の形成方法を提供する。【解決手段】方法は、粉体系皮膜を基板（１２）上に設ける工程と、表面連通細孔を有する多孔質皮膜を形成するするために粉体系皮膜を８００℃超１２００℃未満の温度で熱処理する工程と、溶浸皮膜を形成するために多孔質皮膜の表面連通細孔の少なくとも一部に溶浸材料を溶浸する工程と、耐環境コーティング（２０）を基板（１２）上に形成するために溶浸皮膜を１２００℃超１５００℃未満の温度で焼結する工程とを含む。【選択図】図２
