Abstract
A novel method to protect steel by the application of cements containing with zinc and graphite powders was proposed. The availability of the proposed method was examined by the surface observation of steel and measurement of corrosion potential. Mechanistic studies of the proposed method were also performed on the basis of the anodic polarization curves. The presence of graphite powder decreased the necessary amount of zinc for protection of steel. The polarization curves indicate that the presence of graphite powder greatly increased the anodic current of zinc dissolution.
