Abstract: A turbomachine seal plate includes a substrate with a first material that defines a surface having a substrate width. The substrate includes a first terminus extension that is raised and extends from a terminus portion of the substrate. The first terminus extension extends outwardly relative to the surface up to a terminus extension height. The turbomachine seal plate also includes a coating having a second material that covers the surface of the substrate and defines a coating width. The coating abuts a side of the first terminus extension. The coating width can be substantially equal to the terminus extension height.
