ABSTRACT:
In the pursuit of the forming of light composite materials which may be substituted for metal without loss of strength, composites have been manufactured from silicon carbide fibers in a titanium matrix. Titanium diffuses into the given boundaries of the silicon carbide and degrades it. Yttria has been sandwiched between the titanium and silicon carbide, to provide a reaction skin of yttria which reduces the extent of diffusion. The present invention oxidizes the silicon carbide prior to applying the yttrium and thus further improves the resistance to diffusion.
