RESUMEN: En un país tan extenso y de tanta diversidad geográfica como Colombia no se había realizado un estudio de corrosión atmosférica que incluyese ambientes de diferente agresividad. En este trabajo se evaluó el comportamiento del acero al carbono, acero galvanizado y aluminio expuestos durante 8 meses en 21 sitios colombianos de diferente agresividad. Además, se realizó una clasificación bimensual de las atmósferas utilizando la técnica CLIMAT. Finalmente, se correlacionaron las velocidades de corrosión halladas en los distintos materiales con variables atmosféricas medidas en los sitios de muestreo como temperatura, humedad relativa y concentración de cloruros y sulfatos.
ABSTRACT: In Colombia, a country with a wide geographical diversity, it has not been yet performed an atmospheric corrosion study including sites with different aggressiveness. In this paper, behavior of carbon steel, galvanized steel and aluminium exposed during 8 months in 21 Colombian sites of different aggressiveness was evaluated. Furthermore, using CLIMAT method, a bimonthly classification of atmospheres was made. Finally, corrosion rate of materials were correlated with atmospheric parameters measured in test sites as temperature, relative humidity, and sulphates and chlorides concentration
