Samples of alloy 800 H (UNS N08810) and alloy 617 (UNS N06617) were oxidized in a simulated process gas atmosphere. The principal elements of the gaseous environment were 50% H2O , 35% H2 and 5% of CO2, CO, and CH4, respectively. The experiments were carried out at temperatures from 850°C to 950°C for exposures ranging from 600 to 5000 hours. After the exposure, the alloy surfaces showed compact oxide layers, which resulted in a depleted zone of oxidizing element; in the substrate layer. Using Electron Probe Microanalysis (EPMA), concentration profiles and thy extension of the depleted zone were measured. Calculated theoretical profiles were then fitted to that EPMA-measured profiles, using Fick’s second law of diffusion and resolved by a finite different method... Keywords: Alloy 800 H, alloy 617, concentration profiles, chromium, diffusion
