“…13) Matsumoto et al sug- gested that the cathodic CD on steel was smaller in MgCl 2 solution as compared with NaCl solution. 14) They assumed that the decrease of cathodic CD in MgCl 2 solution is due to an insulating product of Mg(OH) 2 covering the bare steel surface. We assume that the decrease in cathodic CD is due to the increase in thickness of corrosion products, the formations of zinc corrosion products and Mg and Ca compounds (CaMg(CO 3 ) 2 , CaCO 3 , and Mg 5 (CO 3 ) 4 (OH) 2 (H 2 O) 5 ) on the zinc particles.…”

The corrosion protection behavior of an inorganic zinc-rich paint (IZRP) layer on steel after exposure for five years in Okinawa, relatively high-chloride atmosphere, was studied. Zinc particles were uniformly dissolved in the IZRP-coated steel, independent of the distance from the IZRP surface. From XRD, FT-IR, Raman spectroscopy and EPMA analyses, Zn 5 (OH) 8 Cl 2 H 2 O and ZnO were generated in the entire corrosion layer. Mg and Ca were observed in the outer area. We proposed the corrosion process of IZRP-coated steel from a detailed analysis of the corrosion products.
