对商业钛海绵 (>99.7%) 的氢等离子弧熔化 (HPAM) 进行了检查。海绵钛的主要杂质为Fe、Al、Cl、Mn。 HPAM 比 Ar PAM 可以更有效地减少这些主要杂质。其他少量杂质也有被HPAM降低的趋势。另外，发现各去除程度可归因于由初始杂质浓度的差异引起的不同的精炼效果。由于HPAM独特的精炼效果，高温等离子弧中解离和活化的氢原子被认为在熔化过程中发挥着重要作用。
Hydrogen plasma arc melting (HPAM) of commercial Ti sponges (>99.7%) was examined. Ti sponges had main impurities such as Fe, Al, Cl and Mn. These main impurities could be reduced more efficiently by HPAM than by Ar PAM. Other small amount of impurities also had a tendency of reduction by HPAM. In addition, it was found that each removal degree is attributable to a differential refining effect caused by the difference of initial impurity concentration. For the unique refining effect of HPAM, dissociated and activated hydrogen atoms involved in the high temperature plasma arc are considered to play an important role in the melting process.
