Abstract:
HIGH TEMPERATURE NICKEL BASE ALLOYS ARE METALLIZED WITH A MIXTURE OF POWDERS CONSISTING OF 60-90 WEIGHT PERCENT ALUMINUM AND 10-40 WEIGHT PERCENT TUNGSTEN. THE COATED ALLOYS ARE SUBJECTED TO A DIFFUSION HEAT TREATMENT TO FORM A TUNGSTEN-MODIFIED, ALUMINUM-RICH INTERMETALLIC. DISPERSION STRENGTHENED NICKEL BASE ALLOYS ARE COATED WITH A LAYER OF NICKEL AND SUBJECTED TO A DIFFUSION HEAT TREATMENT PRIOR TO APPLICATION OF THE ALUMINUM-TUNGSTEN MIXTURE.
