The purpose of this work is to study the behavior of electroless Ni coatings on SAE 1020 steel in aqueous 4% NaCl solution. An aqueous solution with NiSO46H2O (Nickel Sulfate),NaH2PO2.2H2O (Sodium Hypophosphite), C3H6O3 (Lactic Acid), C3H6O2 (Propionic Acid) Pb(NO3)2 (Lead Nitrate) as the basic ingredients of the bath was selected for the autocatalytic deposition of Ni with an average deposit rate of...
Key Words: Electroless nickel, mild steel corrosion, heat treatment, hardness.
