摘要：

Self-healing protective films were prepared on a zinc electrode previously treated in a Ce(NO3)(3) solution by modification with Na3PO4 and Ce(NO3)(3.) The protective and self-healing abilities of the films were examined by polarization measurements and observation of pit formation after the electrode was scratched with a knife-edge crosswise and immersed in oxygenated 0.5 M NaCl at 30 degreesC for many hours. Mechanisms of the protective and self-healing activities were discussed using X-ray photoelectron spectroscopy and electron-probe microanalysis. The protective and self-healing abilities of the films prepared on the zinc electrode by treatment in the Ce(NO3)(3) solution and modification with Na3PO4 Plus Ca(NO3)(2), Mg(NO3)(2), Zn(NO3)(2) or Ce(NO3)(3) were summarized.
