| Abstract: | An accurate and fast measurement for the performance of phosphate coatings is favorable to adjust phosphating process so that to produce phosphate coatings with good corrosion resistance. The protectiveness of phosphate coatings is related to the porosity of the coatings. The electrochemical techniques for measuring the porosity of phosphate coatings by linear polarization and EIS for evaluating the protectiveness quantitatively were summarized. A modified EIS method for easily and quickly evaluating the performance of phosphate coatings was also introduced. The effect of the solutions used for measuring process on the measared porosity of phosphate coatings was analyzed. Application prospect of electrochemical measurement technique in phosphating industry was presented. |
