Resumen
NAJIH, R.; CHTAINI, A. y OULFAJRITE, H.. Preparation and Physicochemical Characterization of Natural Phosphate and Kaolin Coatings in Stainless Steel. Port. Electrochim. Acta [online]. 2011, vol.29, n.1, pp.39-45. ISSN 0872-1904.
The inhibition efficiency of natural phosphate and kaolin systems in controlling corrosion of stainless steel in HClO4 (0.1 M) solution has been evaluated by electrochemical polarization methods, and electrochemical impedance spectroscopy. The electrochemical data show that the corrosion resistance is greatly enhanced after surface modification. The best protection is obtained with natural phosphate. The uniform coatings of phosphate and kaolin on iron substrates were obtained by electro deposition.
