摘　　要：采用真空熔炼、惰性气体雾化的工艺生产焊膏用铝基钎料（AS-1）粉末.在雾化压力1.2 MPa、熔液流量3.0 kg/min和熔液温度780℃的工艺条件下,所制备的钎料粉末粒度小于0.15 mm的质量分数大于85%,其中0.045~0.15 mm粉末占成品粉质量分数90%以上,粉末呈球形.所制备的钎料粉末达到了铝焊膏用钎料的性能.This paper deals with a gas atomization process of aluminum filler metal for brazing paste, studied the relation between particle size and atomizing pressure, the melting aluminum temperature, leaking rate. Under the conditions of atomizing pressure of 1.2 MPa, flow rate of 3.0 kg/min for melting aluminum and the temperature of 780℃ the mass fraction of prepared filler powder of particle size less than 0. 15 mm is over 85%. The filler powder prepared has reached the property of powdered aluminum based filler metals.
