ABSTRACT:
A pre-treating method for plating a Fe—Mn—Al alloy surface includes the steps of: cleaning a Fe—Mn—Al alloy surface with ultrasonic energy; heat-degreasing the Fe—Mn—Al alloy surface with a basic solution for removing accumulated grease; deterging the Fe—Mn—Al alloy surface with an acid solution for eliminating corrosion produced in previous high temperature conditions; electrolyzing the Fe—Mn—Al alloy surface with a basic solution for removing an oxidative layer; and neutralizing the basic solution remained on the Fe—Mn—Al alloy surface with an acid solution; and plating the Fe—Mn—Al alloy surface with corrosion-resisting materials.
