Abstract: A surface processing method for a high hardness and abrasion resistant zinc alloy surface of imitation plating hexavalent chromium, includes following steps. Perform polishing for surface of zinc alloy workpiece, and leave it to dry; place the dried up workpiece into Hydrofluoric Acid solution to raise adhesion; wash the activated workpiece clean with pure water, and then place it in a silane oxide solution, to process it into silane conversion film; place the workpiece into an electrophoresis solution to perform electrophoresis, to achieve an electrophoresis application layer; use an UF solution to wash the workpiece; perform pre-drying for the workpiece; perform UV curing for the workpiece; hang the workpiece in a PVD furnace, perform sputtering of chromium, to form a metal-ceramic composite film; and perform PVD on surface of the workpiece, to deposit a layer of transparent DLC film on the workpiece.
