  1. ( 3 ) the most principal factors that influence the supersonic atomization process include the flow ratio of the gas - liquid metal ( gmr ) value, the flow of atomizing of gas and the range of the inverse vortex taper. the more of the value of three factors, the more advantage they are for the atomization and the more fine the powders are. ( 4 ) the produced powders are the best in efficient atomization efficiency, particle diameter, particle shape and dispersion when the solder alloy is zhl63a, atomizing medium is n2, the protrusion h = 6. 0mm, atomizing gas pressure p = 100mpa, over - heat temperature t = 167 ( t = 350 )

    研究結果表明: ( 1 )超音速霧化器的氣體流場在導液管下形成一個倒渦流錐,在二維空間上呈軸對稱的雙峰分佈,負壓形成於這個倒渦流錐內; ( 2 )修正後的霧化氣體速度公式可以滿足超音速霧化的要求; ( 3 )影響超音速霧化工藝最根本的因素有氣液量流率比( gmr )的大小、霧化氣體流量和倒渦流錐范圍,三個因素的值越大,對形成細粉越有利; ( 4 )在焊錫合金為zhl63a ,霧化微n _ 2 ,導液管突出高度取h = 6 . 0mm ,霧化氣體壓力取p = 1 . 0mpa ,合金過熱度取t = 167 ( t = 350 )時,所制得的粉在有效霧化率、顆粒球形度、粒度及其離散度三個方面綜合性能最好。
