Based on the essence of resistance,and concepts of lattice vibrations, phonons and lattice distortion, the influence of electrical resistivity on corrosion rate of zirconium metal has been investigated in this paper. The correlation of the corrosion rate and electrical resistivity has been calculated. It is found that along with the electrical resistivity increasing, the corrosion rate decreases. The change of the lattice distortion results in the change of the electrical resistivity. For the nanocrystallin...
