Einfluss der Schleifbehandlung auf das Korrosionsverhalten von Chrom-Nickel-Stählen

Abstract

Mechanical grinding of stainless steels is often used for decoration purposes, for instance in the interior decoration. However, this treatment can cause problems regarding the corrosion resistance. During investigations of the influences of processing parameters of industrial grinding it was shown, that roughness only is not the expected crucial parameter for the corrosion resistance. The variation of different grinding parameters and also the type of abrasives have a substantial influence. Beside the long term tests electrochemical investigation at the ground surfaces are presented. The different corrosion susceptibility of the surfaces could be proven by means of electrochemical noise measurements.
