This work has been supported by European Union within the frame of the EU Research Program “Standards Measurement and Testing”, project SMT4-CT97-2184 “DEFCYL: Detection of DEFects in CYLindrical surfaces”.In this report a classification of the main surface structures found on fine metallic wires is carried out (between ∼20 and 500 μm in diameter). For this, we have analyzed a series of wires of different metallic materials, diameters and production environments by scanning electron microscopy, atomic force microscopy, and confocal microscopy. A description and the images of the structures is given and, in addition, a nomenclature to be used by manufacturers, customers and researches is proposed. With this information the surface quality of fine metallic wires may be improved in a fabrication level. One of the objectives of this catalogue of defects is to serve as a basis for measuring the quality of the surface of the wires during the production process and the development of a measuring device for that purpose.engjournal articlehttp://dx.doi.org/10.1016/S0169-4332(01)00322-1http://www.sciencedirect.comopen access535DefectsWiresSurface StructureRoughnessSurface DefectsTribologyMetallic SurfacesÓptica (Física)2209.19 Óptica Física
