To fabricate calcium-phosphate (CaP) coatings with good corrosion resistance on AZ31B alloys via micro-arc oxidation (MAO) treatment, hexamethylenetetramine (HTMA) was selected as an effective MAO additive of magnesium alloys. The influences of HTMA concentrations on formation mechanism and coating...
