摘要

Complex pickling and polishing process comprises: (i) pickling metal parts, especially copper-containing colored metals; (ii) polishing in a centrifugal vibratory grinding device for a determined time to achieve the maximum contrast between image segments; and (iii) coarsely polishing the image relief before further processing in the grinding device.
