Abstract: Recently, a vast amount of exploring experiments have been made to solve many deadly defect of existing trivalent chromium plating processes and promote to finally substitute the trivalent chromium for the hexvalent chromium plating. Technical scheme which we substitute the amorphous chromium alloy deposition for the pure chromium is determined step by step and process of amorphous CrFeC alloy plating from trivalent chromium plating bath has been developped successfully. The deposition maintains standard of traditional hexvalent chromium deposition in properties of wearresistance and corrosive wear resistance. Moreover, it completely eliminates serious enviromental pollution and has certain advantages of technological property and production cost.
