چکیده انگلیسی
We have studied the variation in the work function of the surface of sputtered cleaned 316L stainless steel with only a very thin residual oxide surface layer as a function of grain orientation using X-ray photoelectron emission microscopy (XPEEM) and Electron Backscattering Diffraction. The grains are mainly oriented [1Â 1Â 1] and [1Â 0Â 1]. Four distinct work function values spanning a 150Â meV energy window are measured. Grains oriented [1Â 1Â 1] have a higher work function than those oriented [1Â 0Â 1]. From core level XPEEM we deduce that all grain surfaces are Cr enriched and Ni depleted whereas the Cr/Fe ratio is similar for all grains. The [1Â 1Â 1] oriented grains show evidence for a Cr2O3 surface oxide and a higher concentration of defective oxygen sites.
