✦ Synopsis
Glass-bead blasted stainless steel sheets are used in recent time for many applications in architecture or design of machines. If chloride can be accumulated on the surface, glass-bead blasted stainless steel show a worse corrosion behaviour than ground stainless steel. The corrosion behaviour of glass-bead blasted stainless steel is characterised by electrochemical, topographic and roughness investigations. The results of glass-bead blasted stainless steel will be compared with results of other surface treated steels like ground, structure rolled, sand-blasted and electropolished stainless steel. It is shown that not only the roughness parameter R a has an influence on the corrosion behaviour but also the shape of the valleys and peaks, which are produced during different surface treatments. The investigations lead to advices for the use of these materials in practice.
