Abstract:
     The invention is related to simple and rapid engraving technology on metal material. Its main charater is that it protects the unprocessing portion of the metal material with photographical sensitilization or lacquor painting and processes with reverse brush plating technique by utilizing the electrolysis theorem. As compared with the existing processing method, it has the merits of guarantee quality, rapid speed, low cost, controllable depth, simple operation and wide appliance. It is especially suitable to use in the production of nameplate and printing circuit, the engraving (words or figures) and mould processing for high hard alloy workparts.
