Electrochemical corrosion experiments can provide a variety of data related to the pitting, crevice corrosion, and passivation behavior for specific sample/solution combinations. These data are useful in selecting materials and/or determining how manufacturing processes affect corrosion properties.
All corrosion is an electrochemical process of oxidation and reduction reactions. Therefore, controlled electrochemical experimental methods are used to characterize the corrosion properties of metals and metal components in combination with various electrolyte solutions. Electrochemical corrosion experiments measure and/or control the potential and current of the oxidation/reduction reactions. Several types of experiments are possible by manipulating and measuring these two variables through the use of a potentiostat.
MEE can perform potentiodynamic experiments to provide a variety of data related to the pitting, crevice corrosion, and passivation behavior for specific sample/solution combinations. Accelerated corrosion tests, such as salt spray or high-humidity exposures, are often useful to simulate a failure mechanism or evaluate potential corrective measures. Microbiological testing can be performed when microbiologically influenced corrosion (MIC) is suspected to have contributed to the corrosion. Chemical analysis methods, including spot tests and surface analysis, can also be useful to evaluate contamination and surface conditions that affect corrosion performance.
