| description | An improved gas seal between a stationary member and a movable member, one of which includes an abrasive tipped projection directed toward a surface of the other, for example a turbine engine blade and a cooperating shroud member, is provided through an improvement in the abrasive tip. Such improved tip of the projection is a composite of inner and outer tip portions, the inner portion comprising an alloy resistant to oxidation, sulfidation and thermal fatigue at operating temperatures and the outer tip portion comprising a matrix entrapping a plurality of abrasive particles which protrude from the matrix toward the surface of the other member. The inner tip portion is bonded with the metallic body of the projection and the outer tip portion is deposited on the inner tip portion. |
