if the alloy is in itself sensitive to the oxygen, then not only in atomization time must take the measure, when melting should better also use the vacuum melting.
如果合金本身对氧非常敏感,则不仅在雾化时要采取措施,在熔化时最好也采用真空熔炼。
methods:the four major factors including ashing time, ashing temperature, atomization time and atomization temperature were arranged and tested according to the l16(44) orthogonal table.
方法:应用l16(44)正交表安排石墨炉原子吸收光谱法测定化妆品中铬时的灰化温度、灰化时间、原子化温度和原子化时间并进行实验。
regarding majority alloy, so long as in atomization time adopts reduced and the oxygen contact, can achieve reduces in the powdered alloy the oxygen content goal.
对于大多数合金,只要在雾化时采取减少与氧的接触,就能达到降低合金粉末中氧的含量的目的。
