本文采用真空熔化法诸方案和惰性气体熔化法测定了各种钛和钛合金样品中的氧,都获得了准确的结果。用真空熔化法测定钛和钛合金中氧,以镍熔剂法为好;用惰性气体熔化法可采用镍熔池法。本文还对真空熔化法诸方案的考察、消除活性升华物的影响、方法的准确度与惰性气体熔化法的优点等问题进行了讨论。 In this paper, vacuum melting methods and inert gas melting scheme were used to determine the oxygen in various titanium and titanium alloy samples, and the accurate results were obtained. The vacuum melting method for the determination of oxygen in titanium and titanium alloys, nickel flux method is better; with inert gas melting method can be used nickel bath method. This article also discussed the vacuum melting method of various programs to eliminate the impact of the active sublimate, the accuracy of the method and the advantages of the inert gas melting method and other issues were discussed.
