Tuxpan is a port with economic and industrial important activity, has subject to the process of atmospheric corrosion of metal structures such as boats, ships, oil platforms and Thermoelectric. The main purpose of this paper is to evaluate the Atmospheric Corrosion of Tuxpan Veracruz, it was necessary to install a display panel with carbon steel specimens (Ac -R), galvanized steel (zinc ), aluminum and copper in order to evaluate them in every season by electrochemical methods (electrochemical impedance spectroscopy (EIS), linear polarization resistance (LPR) and potentiodynamic polarization curves (CP) ) and at the end of the year by gravimetric techniques as established by CLIMAT and ISO methodology. The results show the aggressiveness of the marine atmosphere, mainly zinc and carbon steel due to aggressive agents such as chlorides and SiO2 (silica). XRD analysis shows the presence of metal oxides formed on the metal substrate surface.
