摘要: Ru-doped NiCoCrAlYTa alloy and other undoped were oxidized isothermally under a temperature range of 1173-1423 K. Oxidation kinetic constant kp was determined for each alloy. Further, samples doped treated in cyclic oxidation at temperatures 1223 1323 Scanning Electron Microscopy analysis performed on the samples. The addition 1.0% mass Ru powder NiCoCrAlYTa, not detrimental thermal conditions.
