Carbon fiber reinforced nickel matrix composite having an intermediate layer of metal carbide
Abstract
Abstract COMPOSITE ARTICLES HAVING A NICKEL BASE METAL MATRIX REINFORCED WITH A PLURALITY OF HIGH STRENGTH, HIGH MODULUS CARBON FIBERS HAVING A THIN, INTERMEDIATE LAYER OF A METAL CARBIDE DISPOSED ON THE FIBER SURFACES. SUCH COMPOSITES ARE CHARACTERIZED BY IMPROVED THERMAL CYCLING CHARACTERISTIC AND ARE PRODUCED BY IMMERSING A PLURALITY OF HIGH STRENGTH, HIGH MODULES CARBON FIBERS IN A MOLTEN METAL BATH CONTAINING AN ALLOY CONSISTING ESSENTIALLY OF AT LEAST ONE METAL CAPABLE OF REACTING WITH CARBON TO FORM A METAL CARBIDE AND AT LEAST ONE ACID-SOLUBLE METAL WHICH DOES NOT REACT WITH CARBON TO FORM A METAL CARBIDE AND WHICH ACTS AS A VEHICLE OR CARRIER FOR THE CARBIDE-FORMING METAL; SOAKING THE FIBERS IN SAID MOLTEN METAL BATH FOR A TIME SUFFICIENT TO EFFECT REACTION BETWEEN THE FIBERS AND THE CARBIDE-FORMING METAL TO PRODUCE A METAL CARBIDE COATING ON THE SURFACE OF THE FIBERS; REMOVING UNREACTED METAL FROM THE METAL CARBIDE COATED FIBERS SO-PRODUCED; AND INCORPORATING THE FIBERS INTO A NICKEL BASE METAL MATRIX.
