Abstract

PURPOSE:To impart corrosion resistance by forming a manganese-manganese hydrate oxide layer or further oil coating layer on the surfaces of steel material. CONSTITUTION:Mn is electroplated to thicknesses of 0.4 to 8mu on steel material surfaces. After the plating surfaces are rinsed, they are dried and the steel material is dipped in an aqueous solution containing hexad Cr ions up to 5g/l to saturated concentration. Or it is subjected to cathode electrolysis treatment at current density of 2A/dm<2> or over in the same solution to form a Mn hydrate oxide layer. The Mn- plated surfaces are stabilized by the Mn hydrate oxide layer to considerably improve corrosion resistance. Hexad chrominum ions do not exist in this Mn-hydrate oxide layer which is only the magnanese hydrate oxide layer, but it has a property of easy adsorbing oils and fats and therefore rust preventive oil or lubricating oil is coated to thicknesses of 0.1 to 5g/m<2> to additionally improve ths corrosion resistance.
