Abstract
Method of producing a profiled abradable coating on a substrate in which an abradable ceramic coating composition is applied to a substrate using direct-write technology, or plasma sprayed onto the substrate through a mask or by use of a narrow foot-print plasma gun. These methods of producing abradable coatings are performed in the absence of a grid.
Claims9
Method of producing a profiled abradable coating on a substrate comprising thermal spraying a profiled bond coat composition through a mask in the absence of a grid or web on the subwstrate followed by plasma spraying a ceramic or metallic topcoat composition conforming to the profiled bond coat.
