摘　　要：功率超声施加于金属熔体中，可以在极短时间内实现纤维与金属的复合，制备出高性能复合材料。液态金属在超声作用下能渗入颗粒预制件中或与颗粒均匀混合。超声浸镀可以实现钢丝镀锌、镀铝。利用超声电解法能够制备出超细金属粉。igh-intensity ultrasound entering a molten metal, fibers can combined with the metal shortly, which results in the composites of excellent mechanical property. Under the function of ultrasonic infiltration, a liquid metal can permeate into a particulate perform or can be mixed with the particulates homogeneously. Zinc or aluminium plating on steel wire can be completed by the ultrasonic infiltration coating. Ultrafine metal powder can be prepared successfully by means of an ultrasonic electrolysis process.
