Abstract:

Removal of stainless steel compressor blades from low carbon steel discs during engine overhaul is frequently made difficult because of corrosion in the slots into which the blades are fitted. It was suggested that a thin coating of G392 grease silicone-graphite applied to the fir tree section of the blade prior to assembly of the unit might facilitate disassembly. This investigation was conducted to determine the effect of G392 grease on the corrosion of stainless-low carbon steel couples. It was concluded that G392 grease did not accelerate corrosion of low carbon steel coupled to stainless and that the grease might make it easier to remove the blades since the anti-seize portion of the grease would still be effective even if the silicone portion was lost through heating.
