Nickel-molybdenum bonded titanium nitride-titanium carbide
Abstract
Abstract SOLID COMPOSITIONS OF FROM 49.5 TO 94 VOLUME PERCENT TITANIUM NITRIDE, AND 5 TO 49.5 VOLUME PERCENT TITANIUM CARBIDE BONDED WITH FROM 1 TO 15 VOLUME PERCENT OF METAL COMPOSED OF 20 TO 50 VOLUME PERCENT NICKEL AND 50 TO 80 VOLUME PERCENT MOLYBDENUM, THE COMPOSITION HAVING AN AVERAGE GRAIN SIZE OF LESS THAN 2 MICRONS AND A DENSITY OF AT LEAST 99 PERCENT OF THEORETICAL ARE PREPARED BY HOT-PRESSING AN INTIMATE MIXTURE OF FINE POWDERED TITANIUM NITRIDE, TITANIUM CARBIDE AND METAL AT A TEMPERATURE BETWEEN 1650* AND 1900*C. AND A PRESURE BETWEEN 1000 AND 5000 POUNDS PER SQUARE INCH. THE DENSE COMPOSITIONS ARE VERY STRONG AND HARD AND POSSESS A VERY DESIRABLE COMBINATION OF OXIDATION RESISTANCE, WEARRESISTANCE, SCRATCH-RESISTANCE AND CORROSION RESISTANCE.
