In contrast to most other manufacturing technologies, in electrochemical machining processes only slight changes material characteristics the rim zone of workpieces are stated literature. Due physical active principle, no thermo-mechanically induced phase or evolution a so-called white layer were ever observed. Aside this fact, not inconsiderable number smaller modifications found past. The common effects occurring during generation passive on surface by changing local chemical composition material, selective dissolution one metallic phase, occurrence flow marks. Consequently, last two also change roughness as marks and dissolved phases represent ditches surface. Therefore, article, presented. Their influence integrity is exemplarily analyzed for heat-treatable steel 42CrMo4. addition, first steps correlation loadings that promote these changes, process signature, made. Based this, different parameters can be compared set up properties purposefully.
