对钢表面进行不同的热处理,并通过表面敏感反射模式 EXAFS 实验在 Cr 和 Fe K 边缘异位和原位研究了该过程。虽然异位研究的样品是在惰性载气(N 2 或 Ar)中使用不同的添加剂(例如氢气 (H 2) 和甲硅烷 (SiH 4))在传送带炉中在 600 至 900 C 的温度下进行热处理,但原位抗氧化处理是在高真空环境(p< 10-6 mbar)中进行的。虽然异位实验表明需要使用 SiH 4 添加剂才能将钢还原为金属状态,但真空处理在温度高于约 10 ℃ 时似乎是成功的。 900℃。
Different thermal treatments were performed for the anti-oxidation of steel surfaces, and the processes were investigated ex-situ and in-situ by surface sensitive reflection mode EXAFS experiments at the Cr and Fe K-edges. While the samples for the ex-situ studies were heat-treated in a conveyor belt furnace at temperatures between 600 and 900 C in inert carrier gases (N 2 or Ar) using different additives such as hydrogen (H 2) and monosilane (SiH 4), the in-situ anti-oxidation treatments have been performed in a high vacuum environment (p< 10-6 mbar). While the ex-situ experiments suggest that SiH 4-additives are needed for the reduction of the steel to a metallic state, the in-vacuum treatments appear successful for temperatures above approx. 900 C.
