HIGH-TEMPERATURE COMPOSITE MATERIAL FOR SEALING COATING Russian patent published in 1999 - IPC

Abstract RU 2133297 C1

FIELD: metallurgy, more particularly sealing composite materials used as seals intended for use on compressor components and gas-turbine engine turbine. SUBSTANCE: material comprises, wt %: nickel alloy, 30-40; zirconium dioxide, 40-50; high-temperature solder, 3-8; and composite containing nickel intermetallide, boron nitride, graphite, and phosphate binder, the balance. Gas-thermal spraying of such composition makes it possible to prepare seal which has desired heat resistance, thermal shock resistance and tearing cohesion strength. EFFECT: improved properties of the high- temperature composite material. 2 cl, 1 ex, 1 tbl
