Pretreatment of Steel Surfaces — •Christian Holzheu, Matthias Laske, and Othmar Marti — Institute of Experimental Physics, University of Ulm, 89069 Ulm, Germany

Steel is used for many purposes in several industrial fields. To improve the material properties several pretreating methods were tested. Especially laser treating was investigated. The characterization of the effected changes was done by performing different surface measurements. XPS (x-ray photoelectron spectroscopy) and Auger method were used to define the chemical structure, XRD (x-ray diffraction) to characterize the crystalline device. The Roughness was investigated by AFM (atomic force microscope).
