    Abstract: PROBLEM TO BE SOLVED: To achieve an abrasive end portion for a seal mechanism of a gas turbine engine that receives a high degree of wear which is more durable, and the production of which is less expensive. SOLUTION: An abrasive end portion 28 includes a zirconium oxide wear coating 44 which is harder than a abraded seal surface such that it is able to grind the abraded seal surface, and which directly covers the top which has substantially no macrogrit. The coating 44 has a pillar-like structure and contains a stabilizer of approximately 3 wt.% to approximately 25 wt.%. The stabilizer may be selected from yttrium oxide, magnesium oxide, calcium oxide, or a mixture of these materials.

    Abstract: A gas turbine engine seal system includes a rotating member 12;30 having an abrasive tip 28 disposed in use in rub relationship to a stationary, abradable seal surface. The abrasive tip comprises a zirconium oxide abrasive coat 44 having a columnar structure that is harder than the abradable seal surface such that the abrasive tip can cut the abradable seal surface. The coat 44 comprises zirconium oxide and about 3% to 25% of a stabilizer selected from yttrium oxide, magnesium oxide, calcium oxide or mixtures thereof.

    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.
