Abstract
Effects of coating treatment of metallic Cu and Ni-P film on SiC fiber for Al/SiC composite were studied. Ni-P and Cu were deposited on SiC fiber by electroless plating method. The morphology of coated film and wetting behavior of composite were analysed by SEM The coating treatment on SiC fibers improved wettability of Al melt on SiC comparing to the non wated SiC fiber, and especially Ni-P coating turned out most effective. This improved wettability seems strongly concerned to the increase of chemical reactivity between coating layer and Al matrix. The reaction between Al melt and coated metallic film forms eutetic melt, and those reaction may accelerates the break down of Al oxide film to promote wettability positively.
