Abstract

PURPOSE: To prevent a turbine rotor from corrosion, by flame spraying powder of silicon, aluminum and polyester to a shaft sealed part of the terrestrial heat turbine rotor.
CONSTITUTION: Sealing steam passing through a labyrinth packing 3b and the outside air passing through a labyrinth packing 3c enter a gland vent chamber 6. To the shaft sealed part of a turbine rotor 2, powder consisting of 3W10wt% silicon, 45W55wt% aluminum and the rest of polyester is flame sprayed. In this way, a seal treatment process is not required to obtain an economical state, prevent corrosion of the turbine rotor due to the terrestrial heat steam and the atmospheric air and increase a life of the turbine rotor. Further at the time of disassembly and repair, the flame sprayed film can be easily removed.
