摘要：

The effects of several plating variables, current density (CD), bath composition and additives on the corrosion properties of electrodeposited Ni-Mn coatings on mild steel have been investigated in 3% NaCl. Results indicate that the plating variables have marked effects. With different additives. the crystal growth pattern is altered resulting in different corrosion characteristics. gamma Fe2O3. H2O, gamma FeOOH and ferrihydrate form the major phases in the corrosion products. Five plating conditions are identified giving suitable Ni-Mn deposits to function as sacrificial coatings for mild steel. Benzene, as additive, is helpful in increasing the Mn content in the deposit.
