• Resumen

  • The classification of the different types of atmospheres through corrosivity indexes is important for the selection of metallic materials and coatings exposed to atmospheric corrosion. Faculty of Chemical Sciences in collaboration with the Institute of Engineering of the Universidad Veracruzana has developed a project for the construction of the Corrosivity Map of the State of Veracruz. Among the activities of the project is the evaluation of the indixes of atmospheric corrosivity in the city of Tuxpan Veracruz, due to the industrial, urban activities and to be located in a coastal area, characteristics that influence the corrosion of metallic materials exposed to the atmosphere. A exposition panel was installed with specimens of aluminum wire on steel screws, copper screws and plastic screws to study corrosivity indexes through mass loss in every season of year, and thus classify the different types of atmospheres; marine, industrial and rural-urban according to the values specified in the standard. The studies were conducted under the ISO 8408, 9223 and 9224 normative. Corrosivity indexes obtained indicate a domain of rural-urban atmosphere product of excessive urban activities in the region. Expected to detect high levels of marine atmosphere by the presence of chlorides and particles resulting City location front of coast. However, corrosivity indexes for marine atmosphere are within the limit allowed by the normative.
