專利摘要 A metal layer such as copper, silver or nickel is coated on a surface of reinforcement particles (aluminum oxide or silicon carbide powder) by electroless plating technique. The metal-coated reinforcement particles with an appropriate volume fraction are inserted into the gap between two metal plates or two metal matrix composite (MMC) plates. The reinforcement particles are stirred into the metal plates or the MMC plates by friction stir welding (FSW) to form a butt weld metal containing reinforcement particles. Or the metal-coated reinforcement particles deposited on the surface of the metal plates or the MMC plates and then are stirred into base material of the metal plates. The metal-coated reinforcement particles are uniformly distributed in a weld metal by such stirring, the coated metal layer on the surface of the reinforcement particles form an alloy with metallurgical bonding.
