High temperature oxidation behavior of aluminide on a Ni-based single crystal superalloy in different surface orientations
An investigation on oxidation behavior of coated Ni-based single crystal superalloy in different surface orientations has been carried out at 1100 °C. It has been found that the {100} surface shows a better oxidation resistance than the {110} one, which is attributed that the {110} surface had a sli...
