AB  - Nano-scale chemical inhomogeneity in surface oxide films formed on a V- and N-containing martensite stainless steel and tempering heating induced changes are investigated by a combination of synchrotron- based hard X-ray Photoelectron emission spectroscopy (HAXPES) and microscopy (HAXPEEM) as well as microscopic X-ray absorption spectroscopy (μ-XAS) techniques. The results reveal the inhomogene- ity in the oxide films on the micron-sized Cr<sub>2</sub> N- and VN-type particles, while the inhomogeneity on the martensite matrix phase exists due to localised formation of nano-sized tempering nitride particles at 600 °C. The oxide film formed on Cr<sub>2</sub> N-type particles is rich in Cr<sub>2</sub>O<sub>2</sub> compared with that on the martensite matrix and VN-type particles. With the increase of tempering temperature, Cr<sub>2</sub>O<sub>2</sub> formation is faster for the oxidation of Cr in the martensite matrix than the oxidation of Cr nitride-rich particles.
