ABSTRACT:
A method for wetting and bonding refractory alumina or aluminosilicate fibers or particles with molten aluminum or aluminum alloys by forming a boron oxidized interface between the fiber and the metal is exists. The method comprises the steps of (a) coating alumina fibers with an effective amount of a thermally decomposable precursor of boron oxide; (b) heating the coated fiber sufficiently to form a boron oxide; and (c) forming a composite with aluminum metal or an aluminum alloy. Thermally decomposable precursors of boron oxide include ammonium pentaborate, ammonium diborate and orthoboric acid.
