CONTOURED BONDCOAT FOR ENVIRONMENTAL BARRIER COATINGS AND METHODS FOR MAKING CONTOURED BONDCOATS FOR ENVIRONMENTAL BARRIER COATINGS
A method of protecting a gas turbine component for operation in a high temperature environment that includes the gas turbine component including a substrate having a silicon-containing layer, wherein the gas turbine component has a curved surface; forming a flexible mask configured to cover the curved surface of the gas turbine component, the flexible mask including a plurality of slots disposed in a pattern; disposing the flexible mask in direct contact with the curved surface of the gas turbine component; applying a bondcoat onto the flexible mask and the gas turbine component, such that bondcoat fills the plurality of slots and contacts the curved surface; and removing the flexible mask by heat or chemical reaction, such that, after removing the flexible mask, the curved surface of the gas turbine component comprises a patterned bondcoat layer in the pattern defined by the flexible mask.
