Notes:
Protective, chromate substitute thin layers on roughened galvanized surfaces produced at OCAS(Arcelor, Belgium) were characterized and compared using Scanning Electron Microscopy(SEM+EDS), Atomic Force Microscopy (AFM), Nanoindentation and X-ray PhotoemissionSpectroscopy (XPS). EDX maps, line scans and point analyses obtained at various places of thesurfaces have shown differences between the CVD and silane nanolayers in the matter of thicknessdistribution and composition. At cross-section specimens the thickness of the layers could beshown. The hardness differences caused by layer thickness variations are hard to follow bynanoindentation as the penetration depth of the indenter is much larger than the thickness of thecoatings. XPS measurements can distinguish between the chemical states of silicon in CVD andsilane coatings
