The effect of sodium nitrate (NaN03) and sodium peroxide (Na202) deposits on the high temperature oxidation of Nimonic-105 (N-105) alloy at 700rj has been studied for a period of 120 h in air. The alloy was more severely attacked by NaN03 than by Na202 due to production of additional oxygen during fluxing reactions and evolution of nitrogenous gases. The scale morphologies were determined on the basis of X-ray Diffraction Analysis, Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Analysis (EDAX).
