BOND COATINGS HAVING A SILICON-PHASE CONTAINED WITHIN A REFRACTORY PHASE

摘要

A coated component (100), along with method of forming the same, is provided. The coated component (100) includes a substrate (102) having 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) includes a silicon-phase (110) contained within a refractory phase (112). The silicon-phase (110), when melted, is contained within the refractory phase (112) and between the surface (103) of the substrate (102) and an inner surface (107) of the environmental barrier coating (108). Such a coated component (100) may be a turbine (28) component (100).
