| Abstract | ||
| In this work the oxidation behavior of both Inconel alloy 600 and coated system (Pt-modified aluminide coating) was investigated in air in the temperatures range 700-1000 C. The oxidation kinetic of inconel alloy 600 and its coated system was found to follow the parabolic law. Large voids were found at the oxide scales-substrate interface and at grains or at grain boundaries. This is due to the chromium depletion in the alloy. The mechanism of void formation has often been attributed to the vacancy condensation. | ||
