“…The chemical nature of the various phases of the phosphate coatings could change depending upon the type of metal (ferrous or non-ferrous) being treated, metal ions present in the solution and the method of deposition [32][33][34][35][36]. Fouladi and Amadeh [34] have reported that the phosphate coating deposited on steel by chemical conversion method using a bath solution that contains magnesium carbonate and phosphoric acid consists of a single phase the phosphate coating deposited on AZ91 Mg alloy using a zinc phosphating bath by chemical conversion coating method consists of two layers: the inner layer is mainly composed of MgZn 2 (PO 4 ) 2 and Mg 3 (PO 4 ) 2 while the outer layer is mainly the hopeite phase (Zn 3 (PO 4 ) 2 ·4H 2 O).…”

A composite conversion coating was prepared on magnesium alloy by the only one-step immersion treatment. The characteristics of the conversion coating were investigated by scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). The results indicate that the composite conversion coating consists of magnesium hydroxide, magnesium phosphate and manganese phosphate. The electrochemical behavior of the conversion coating was investigated systematically by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization measurement in different NaCl solutions. Polarization measurements and EIS results reveal that the magnesium alloy with the conversion coating have better corrosion resistance compared to the bare magnesium alloy in these conditions. And the corrosion rate of the magnesium alloy with conversion coating increases consistently with the chloride ion concentration. In alkaline conditions, the magnesium alloy with conversion coating has superior corrosion resistance by the synergistic effects between Mg(OH) 2 film and conversion coating. Moreover, the electrochemical corrosion mechanism of the magnesium alloy was analyzed with respect to the conversion coating in a Cl -containing environment.

“…These applications can be found in automobile, electronics, aerospace, and mobile phones. However, the use of magnesium alloys is limited by their poor corrosion resistance [1][2][3]. Surface treatments are needed for improving the corrosion resistance of magnesium alloys.…”
