<p>A bond coat (24) is applied to a substrate of a gas turbine engine component the component. A barrier coat (26) is applied atop the bond coat (24). The applying of the bond coat (24) includes: applying a first layer (28) having an as-applied first roughness; and applying a second layer (30) atop the first layer, the second layer (30) having an as-applied second roughness, greater than the first roughness. In the resulting coating system, the first and second layers (28, 30) may have different properties (e.g., greater porosity, pore size, and/or splat size for the second layer (30)).</p> |
