Summary:To provide a bond coating for use with an environmental barrier coating of ceramic constituents, and methods for forming and using thereof.SOLUTION: There is provided a coated component (100) as well as a method for forming the same. The coated component (100) may comprise a substrate (102) with a surface (103), a silicon-based bond coating (104) on the surface (103) of the substrate (102), and an EBC (108) on the silicon-based bond coating (104). The silicon-based bond coating (104) may include a silicon phase (110) contained in a refractory phase (112). The silicon phase (110) is, once melting, included within the refractory phase (112) and included between the surface (103) of the substrate (102) and an inside surface (107) of an environmental barrier coating (108). Such a coated component (100) may be a turbine (28) component (100) in a specified embodiment.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）が、それを形成する方法と共に提供される。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ＥＢＣ（１０８）とを含むことができる。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）を含むことができる。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（１０７）との間に含まれる。このようなコーティングされた構成要素（１００）は、特定の実施形態では、タービン（２８）構成要素（１００）であってもよい。【選択図】図１
