Study of thermal oxidation of NiO on pure Ni, Ni-10%Cr and Ni-9%V tapes

In this work, the thermal oxidation of NiO has been studied at different annealing temperatures and oxygen partial pressure. The oxidation properties of Rolling Biaxial Textured substrate (RABiTS) of pure Ni, Ni-9%V and Ni-10%Cr have been investigated. Oxidation of the substrates either as rolled and recrystallised or as rolled, recrystallised and chemically etched states have been studied. It is found that etched pure Ni forms cube-textured NiO upon oxidation in oxygen flow while Ni-10%Cr and Ni-9%V developed cube textured NiO when oxidised in reduced oxygen partial pressure.
