本文提出了一种两步等离子弧熔炼工艺，第一步在Ar-30%H_2气流下进行，第二步在Ar气流下进行。该过程后的氧含量取决于在Ti熔体中探测的深度。在第二步骤中，Ti熔体的表面区域中的氧含量从1.5质量%降低到0.7质量%。
A two-step plasma arc melting process, comprising a first step under Ar-30 pct H2gas flow and the second step under Ar gas flow, has been newly developed for the deoxidation of Ti melts. The oxygen content after this process depended on the depth probed in the Ti melt. Decrease in the oxygen content from 1.5 to 0.7 mass pct in the surface region of the Ti melt occurred in the second step.
