A method for coating a component. The method includes applying a bond coating to an outer surface of the component using a high-velocity oxy-fuel (HVOF) process. The method also includes roughening the bond coating and applying at least one dense vertically cracked (DVC) ceramic layer to the roughened bond coating.
