Microstructural characterization of Ru-doped NiCoCrAlYTa coupons treated by thermal oxidation

Isothermal oxidation of sintered Ru-doped and undoped Ni-alloy coupons in the range of 1173–1423 K was investigated. To assess the effect of Ruthenium doping, microstructural characterization was performed to compare the samples before and after oxidation treatment at 1173 K. Furthermore, cyclic oxi...

Summary:Isothermal oxidation of sintered Ru-doped and undoped Ni-alloy coupons in the range of 1173–1423 K was investigated. To assess the effect of Ruthenium doping, microstructural characterization was performed to compare the samples before and after oxidation treatment at 1173 K. Furthermore, cyclic oxidation tests on the Ru-doped and undoped coupons were carried out in a thermogravimetry apparatus at 1223 and 1323 K. The addition of 0.8 wt.% of Ru in NiCoCrAlYTa powders sintered coupons does not degrade the material’s resistance to oxidation conditions.
