Summary:Palladium and molybdenum layers deposited onto a WO x substrate in an UHV system have been studied in the field electron and field ion microscope. A different behaviour of these two metals during their high temperature treatment has been observed, viz. the coalescence of palladium layers and evaporation and/or incorporation of molybdenum (probably in the form of a molybdenum oxide). This difference obviously follows from the different nature of the interaction between these metals and the substrate.
