Formation & Properties of Zn–Ca– Mn Tri – Cation’s Phosphate Coating on St37 Steels, M.Sc. Thesis Sharif University of Technology ; Afshar, Abdollah (Supervisor) ; Ghorbani, Mohammad (Supervisor)
Abstract
Addition of heavy metal cations such as manganese and nickel in low zinc phosphating bath increases the corrosion resistance of coatings and provides more suitable substrates for painting (especially electrophoretic painting). In addition, due to accelerating property and low cost availability of heavy metal cations such as Mn, multi– cationic phosphating is cost effective. In the present study, chemical composition and operating parameters of zinc - calcium - manganese Tri- cationic phosphating solution were optimized. Then the effects of various parameters such as phosphating time, bath temperature and pH on properties of coating were investigated. According to the results, about 1 g/L was...
