Oxidation Process of FeNi42Cr6 Alloy Array Materials

摘要

In this paper, the oxidation process of the VFD array material in wet hydrogen at high temperature was studied. By the aid of SEM, EDAX, and XRD, the effect of temperature, duration, volume and dew point of hydrogen flow during oxidation on weight gain, percentage of the oxide phase, constitution and morphology of oxide scale were investigated, and a suitable oxide technology was obtained, it was as follows: 950°C, 40 ～ 60 min, D.P. 35°C, 8 l/min.
