Abstract
The invention relates to a method for electrochemical processing of at least one workpiece, comprising at least the following steps: a) setting a first flow density during a first phase in an electrolyte, b) retaining the first flow density during a second phase following the first phase, c) increasing the first flow density during a third phase following the second phase to a second flow density at least 30% greater than the first flow density, and d) reducing the second flow density during a fourth phase following the third phase within a maximum of 100 microseconds to a maximum of 1% of the second flow density.
