Abstract
A alloy surface treatment includes dewaxing and deoiling to an alloy surface via a cleaning process; sealing holes on the alloy surface with an organic material; forming a first coating on the alloy surface with a UV curing material; providing a plasma treatment to activate the alloy surface, then providing a PVD process to form a second coating outside the alloy; forming a third coating on the alloy surface with another UV curing material which further includes a toner therein, then forming a fourth coating on the alloy surface with the UV curing material, wherein the toner is provided to match the color of hexavalent-chromium to obtain a hexavalent-chromium imitated product.
