• 要約等: The corrosion protective property of modified iron oxide pigments was investigated by impedance measurements, corrosion weight loss tests, and IR absorption spectrum analyses. Pigments were calcined in three mixture ratios of metal oxide (MO, M=Mg, Ca, Zn) and iron oxide (α-Fe₂O₃). Namely the mole compounding ratios of MO and α-Fe₂O₃ are 3:7, 5:5, 7:3. From the impedance measurements of paint films composed of boiled linseed oil and these pigments, the paint film containing pigment of ZnO+ZnO·Fe₂O₃ indicated a high film resistance (<i>R_f</i>) of about 10⁷Ω·cm². In the weight loss test, the steel was inhibited in the extracted solution. So it was found that the pigment was good corrosion protective pigment. But the pigment containing too much Mg or Ca led the paint film to the deterioration. The deterioration of paint film containing pigment of MgO+MgO·Fe₂O₃ did not depend on pigment concentration, and it is suggested that the decrease of adhesion at the paint film/substrate interface is based on the excess formation of metal soaps. From the values of <i>R_f</i>, the pigments used in this work were superior to simply mixed powder in the same composition.
