<p>A thermal spray composition and method of deposition for abradable seals for use in gas turbine engines, turbochargers and steam turbines. The thermal spray composition comprises a mixture of metal-clad solid lubricant particles and unclad solid lubricants particles for producing an abradable seal used in the compressor section of gas engines, aircraft engines, radial compressors and the like. The metal is selected from alloys of Ni, Co, Cu, Fe and Al, preferably Ni alloys, and the solid lubricant is at least one of hexagonal boron nitride, graphite, calcium fluoride, lithium fluoride and molybdenum disulphide, preferably hexagonal boron nitride or hexagonal boron nitride and graphite.</p> |
