摘要：the process for manufacturing the decorative ueberzuege on metals is mainlyused in the jewelry industry, the crafts and geraetebau. the inventive solution is matkonturentreue decorative layers with a homogeneous thickness of 3 microns to 30microns by an electrochemical reaction and plasmachemischen in pulsed in waessrigenelectrolytes in peaks of 250 v to 750 v, impulszeiten 20 microns s to 2 ms,impulsfrequenzen of 35 hz to 300 hz, impulsstroemen from 20 to 120
a,elektrolyttemperaturen between 318 k and 360 k and medium current densities of 0.1 acm to 1 a cm off.
