Abstract

It was observed that adding TiC nanoparticles (NPs) to zinc coating increased its corrosion resistance. To understand the beneficial role of TiC nanoparticles in suppressing corrosion, we studied the electrochemical behavior of TiC NP-added nanocomposite zinc coating, in comparison with those of coarse-grained and nanocrystalline zinc coatings, in simulated seawater. The surface electrochemical stability and surface electron stability, which are respectively reflected by corrosion potential and electron work function (EWF), were investigated. It is demonstrated that the increased corrosion resistance of nanocomposite zinc coating is ascribed to the fact that the TiC nanoparticles raise surface electron work function of the coating, corresponding to elevated surface electron stability.
