Corrosion rate evaluation of the carbon steel trough electrochemical techniques

Usually the atmospheric corrosion studies are cha­racterized by their long duration, months and even years. However electrochemical techniques have been developed, recent in comparison to other methods, allowing obtain real-time data, including corrosion rate. In this research electrochemical noise and lineal polarization resistance tests are valued, so obtained data were analyzed, relations were establis­hed between the graphics form and the corrosion type, as well as the relationship between the corro­sion data and atmospheric conditions, to find, finally, there is a more consistent behavior when the lineal polarization resistance test is used with the three comb-type electrodes electrochemical monitor
