Abstract: | This work presents a method of preparing single-, double-, and triple-cation ferrite pigments by employing simple chemical
techniques to study their corrosion protection properties. The prepared pigments were characterized using X-ray diffraction
and scanning electron microscopy. All prepared ferrite pigments were evaluated using ASTM methods. Anticorrosive paint formulations
were performed using different prepared pigment loadings. The physico-mechanical and corrosion properties of dry paint films
were examined. The tests revealed that the prepared ferrite pigments show excellent anticorrosive behavior, and that the best
among them in performance are zinc and zinc magnesium. Calcium, zinc–calcium, and zinc–magnesium–calcium ferrites show better
performance in high pigment loadings, while magnesium ferrite pigments show good results only in low pigment loading. |
