Aluminum Metal-Ceramic Matrix Composites Reinforced By Using Electroless Nickel Plating On Ceramic Particles And Fibers

摘要

Metal matrix composites (MMCs) are expected to be new materials with various excellent properties. In general, MMCs are classified into three types by the configurations of the reinforcements such as particulate composite, whisker-reinforced metal and fiber-reinforced metal. Although the industrial use of MMCs has been limited by the complexity of a manufacturing process or the high cost of production, paniculate composites can be manufactured more easily using the melt-stirring method. In recent years a number of oxide and other particles including graphite have been dispersed in a cast metal matrix by liquid metallurgy techniques. Incorporation of ceramic particles in a metal matrix has been shown to improve hardness, tensile strength, compressive strength, wear and abrasion resistance.
