ABSTRACT:
A rotary gas seal in which a first member, e.g., a tip, cooperates with a second member to inhibit gas flow therebetween, the improvement wherein, the tip is provided with a ceramic or metallic coating bonded thereto, the surface of the coating having a plurality of laser-formed depressions and providing a wear-resistant, cutting surface capable of cutting into the second member. Also, a turbine or compressor blade having a tip surface adapted to cooperate with a sealing surface to form a seal between the blade and the sealing surface and a ceramic or metallic carbide coating bonded to said tip surface, the coating having a plurality of laser-formed depressions and providing a wear-resistant, cutting surface capable of cutting into the sealing surface.
