Patent number: 11952317Abstract: An example article includes a substrate and a barrier coating on the substrate. The barrier coating includes a matrix including a rare-earth disilicate extending from an inner interface facing the substrate to an outer surface opposite the inner interface. The barrier coating includes a graded volumetric distribution of rare-earth oxide rich (REO-rich) phase regions in the matrix along a direction from the inner interface to the outer surface. The graded volumetric distribution defines a first volumetric density of the REO-rich phase regions at a first region of the matrix adjacent the outer surface. The graded volumetric distribution defines a second volumetric density of the REO-rich phase regions at a second region of the matrix adjacent the inner surface. The second volumetric density is different from the first volumetric density. An example technique includes forming the barrier coating on the substrate of a component.Type: GrantFiled: October 18, 2019Date of Patent: April 9, 2024Assignees: Rolls-Royce Corporation, Rolls-Royce plcInventors: Ngunjoh Lawrence Ndamka, Li Li, Stephanie Gong, Ann Bolcavage, Taylor K.
