摘要： A carbon fiber reinforced metal matrix composite is produced by depositing a metal boride coating on the surface of the fibers and subsequently immersing the fibers in a molten bath of the metal matrix material. The boride coating is formed by passing carbon fiber through a gaseous mixture of chlorides of the metal and boron in the presence of zinc vapor at elevated temperatures. The subsequent reaction deposits out a submicron lamina of metal boride on the carbon fibers serving to enhance wetting of the fibers by the molten metal, with the lamina preventing chemical reaction between the fibers and metal matrix materials and also providing a strong mechanical bond therebetween.

摘要翻译： 通过在纤维表面上沉积金属硼化物涂层并随后将纤维浸入金属基质材料的熔池中来制备碳纤维增强金属基复合材料。 硼化物涂层通过在高温下在锌蒸气存在下使碳纤维通过金属和硼的氯化物的气体混合物而形成。 随后的反应在碳纤维上沉积金属硼化物的亚微米层，用于增强熔融金属对纤维的润湿，而薄层防止了纤维与金属基体材料之间的化学反应，并且在它们之间提供了强大的机械结合。
