Description
Ni-based superalloy TMS-75 was oxidized at 900°C in air. SEM, TEM and Raman Spectroscopy were used to characterize reaction products. At this temperature, an external non-protective (Ni,Co)O scale plus an extensive internal reaction zone consisting of oxide and nitride phases are formed. Orientation relationships were found between the oxide phases.
