Summary:To provide a bond coating used with an environmental barrier of a ceramic constituent, and a method of forming and using them.SOLUTION: A coated constituent (100) includes: a substrate (102) having a surface (103); a first refractory layer (120) of the surface (103) of the substrate (102); a silicon bond coating (104) of the first refractory layer (120); and an environmental barrier coating (108) of the silicon bond coating (104). The silicon bond coating (104) includes a silicon phase (110) included in a refractory phase (112) and thereby the silicon phase (110), when melting, is included in the refractory phase (112), and between the surface (103) of the substrate (102) and the inside surface (103) of the environmental barrier coating (108).SELECTED DRAWING: Figure 1 【課題】セラミック構成要素の環境障壁コーティングと共に使用するためのボンドコーティング、ならびにそれらの形成および使用方法を提供する。【解決手段】コーティングされた構成要素(100)は、表面(103)を有する基材(102)と、基材(102)の表面(103)の第1の耐火層(120)と、第1の耐火層(120)のケイ素系ボンドコーティング(104)と、ケイ素系ボンドコーティング(104)の環境障壁コーティング(108)とを含む。ケイ素系ボンドコーティング(104)は、耐火相(112)内に含まれるケイ素相(110)を含み、それによりケイ素相(110)は、溶融すると、耐火相(112)内、および基材(102)の表面(103)と環境障壁コーティング(108)の内側表面(103)との間に含まれる。【選択図】図1
