Surface analysis was performed by Auger spectroscopy on mixed (Mo,W) carbides that were synthesized with a 50 : 50 molar ratio of both metals. Because of the molybdenum and tungsten Auger peak overlap in the energy window between 100 and 230 eV, a linear combination of appropriately chosen standard
