Modelling of the atmospheric corrosion of copper in the province of Las Palmas. Studies using classic and electrochemical techniques

Abstract

Simulation of the effects of natural atmospheres on metals using electrochemical techniques together with accelerated tests presents certain characteristics that make it highly interesting from the point of view of the study and prediction of corrosion. It will enable us to forecast the behavior of a metal exposed to a particular environment without the need to perform field test, with a consequent saving in terms of time and financial expenses. The aim of this study is to establish the correlation between the atmospheric corrosion rate of copper (obtained by atmospheric exposure at stations located in the province of Las Palmas, Spain) with the different variables that intervene in the corrosion process. In the same way, for the determination of the mathematical model that best fits the results obtained experimentally and which takes into account the most influential parameters in the corrosion process, the power Law model has been used which generically reproduces the electrochemical process which occurs in atmospheric corrosion.
