| titleOfInvention | Improvements relating to axial-flow compressors |
| abstract | <PICT:0852273/IV(a)/1> A material for coating internal surfaces of the casing of an axial-flow compressor comprises a mixture of hard abrasive grit in a thermosetting synthetic resin. The coating protects the casing from corrosion and also withstands the abrasive action of walnut shell grits used in a high pressure fluid stream for cleaning the compressor. The material, comprising a mixture of between 20 and 35% by weight of a hard abrasive grit such as aluminium oxide, boron carbide or, preferably, silicon carbide of about 500 mesh size and between 65 and 80% by weight of an epoxy or silicone resin, is applied to the surfaces 15 of the casing by spraying, brushing or rolling in at least two coats, each of thickness not exceeding about 0,003 inch. A mixture of about 25% silicon carbide in about 75% epoxy resin is preferred. Each coat is dried at room temperature for about one hour and then baked at about 150 DEG F., for about one hour. A final bake is made at about the operating temperature of the compressor, about 450 to 500 DEG F., for about two hours.ALSO:<PICT:0852273/III/1> Internal surfaces of the casing of an axialflow compressor are coated with a mixture of hard abrasive grit in a thermosetting synthetic resin.
