The corrosion protective properties of various ferrite pigments with the epoxy resin (ER) and linseed oil (LO) were investigated by the electrochemical measurements and weight loss test. The corrosion protective property of the linseed oil-ferrite paints was found to show better than that of the epoxy resin-ferrite paints, since some of them showed the small value of tan δ (about 0.5) and the comparative large value of resistance of paint film (R<SUB>p</SUB>) and of corrosion reaction (R<SUB>θ</SUB>). Especially, the corrosion protective property of Ca ferrite showed the large difference between each system of the epoxy resin and linseed oil. Mg and Fe ferrites showed the good corrosion protective property in both epoxy resin and linseed oil systems. There was seen the mutual relationship between the values of tan δ, R<SUB>p</SUB>, and R<SUB>o</SUB> of coated steel and those of weight loss and polarization curve in extracted solution. It was supposed that the corrosion protective effect of ferrite pigments was dependent on their basicity in the epoxy resin system, and on the inhibitive action of decomposition components of paint film based on their basic property in the linseed oil system, respectively.
