al/sub 2/o/sub 3/ fibers were coated with metallic cobalt by sol-gel method for the purpose of enhancing the wettability of fiber in molten metal and improving the interface properties of metal matrix composite. the al/sub 2/o/sub 3/ short fibers were suspended in a cobalt sol containing cobalt acetate, then dried and reduced in hydrogen atmosphere so as to produce cobalt metal coating on the fibers. the results of x-ray diffraction confirmed that the coating layers were completely reduced to metallic cobalt at 300 degrees c
