Abstract
Effect of coating treatment by metallic Cu and Ni-P on SiC fiber for SiC/Al composite were studied. Ni-P and Cu were deposited on SiC fiber by the electroless plating method. The coating improved wettability of SiC fibers by Al. Coating by Ni-P turned out more effective. The improved wettability seems to be strongly related to the increase in chemical reactivity between the coating layer and Al matrix. The reaction between Al melt and coated metallic film forms in a eutectic melt, which accelerates the break down of Al oxide film and improves wettability.
