Abstract: PROBLEM TO BE SOLVED: To provide a wearing material suitable for the knife edge seal of a gas turbine engine. SOLUTION: Copper powder and boron nitride powder are jointly subjected to plasma thermal spraying to obtain this wearing material composed of about 35 to 50 vol.% copper alloy matrix, about 25 to 55 vol.% BN, and the balance pores and the oxide of the matrix. The copper alloy matrix is a solid solution composed of about 65 to 95 wt.% copper, and the balance nickel. In the meanwhile in which this wearing material is interfered with a knife edge in the presence of lubricating oil in a high temp. state, sparks are not generated, and also, the lubricating oil does not deteriorate. Moreover, the wearing material has suitable abrasive characteristics, by which a good seal is formed.

Abstract: An apparatus for applying segmented ceramic coatings includes means for supporting and moving one or more substrates; one or more heat sources disposed proximate to one or more substrates, wherein at least one of the heat sources is positioned to apply a heat stream to pre-heat a thermal gradient zone on a surface of a substrate; a material deposition device disposed proximate to one or more heat sources, wherein the material deposition device is positioned to deposit a material on a deposition area located behind the thermal gradient zone on the surface; and means for monitoring a surface temperature of one or more substrates.

Abstract: A copper based abradable material for use with knife edge seals is disclosed. The copper base abradable contains a significant amount of a lubricating material such as boron nitride. The material can be abraded by smooth knife edges, is oil compatible, and any abraded material will not cause bearing damage. The material is preferably applied by a thermal spray process. Preferably the material comprises, by volume, 35-50% copper alloy matrix, 25-55% lubricant (preferably BN), balance porosity and matrix material oxides.

Abstract: A gas turbine abradable seal is prepared by plasma spraying an oxidation resistant metallic material and boron nitride. The resultant structure comprises a metallic matrix encompassing a lubricating amount of boron nitride, with porosity of less than about 15 percent and a fabricated surface roughness of less than about 600 microinches. The reduced surface roughness and substantially reduced permeability of this seal provide substantially enhanced engine efficiency, and improved durability.

Abstract: Multiple Port Plasma Spray Apparatus and Method for Providing Sprayed Abradable Coatings An apparatus and method are described for simultaneously thermal spraying at least two types of powders onto a substrate, wherein both powder types are carried by a single spray stream and impacted upon the substrate. According to the invention, the different powder types are injected into the spray stream through separate powder ports in such a manner that there is substantially no mixing of the powder types in the spray stream. The spray system and substrate being sprayed are moved relative to each other to produce a homogeneous sprayed powder deposit.
