Salt spray test results are used to guide the selection of protective coatings but their accuracy and repeatability remain a serious challenge to the engineering community. Electrochemical methods are well suited for corrosion testing and provide results that are more precise and information that is more relevant compared to traditional methods. 

Direct and quantitative determination of corrosion rates can be obtained from a variety of electrochemical measurements such as Linear Sweep Voltammetry, Electrochemical Impedance Spectroscopy (EIS) and Linear Polarization Resistance. Most scientists and engineers prefer EIS due to its speed, accuracy, nondestructive nature and ability to characterize highly-insulating films. The popularity of EIS originates from the ability to conduct tests in the same working environment as the material in question, yielding a more accurate rate of corrosion.

In this webinar, Dr. Luis F. Garfias, Materials and Testing Consultant at Environmental & Corrosion Testing of Materials (USA) will present an overview of current electrochemical methods for corrosion testing, including a novel methodology to measure the Critical Pitting Temperature (CPT) of stainless steels in artificial seawater. Dr. Julia van Drunen, Area Manager at Metrohm Autolab, will then share some insights into EIS corrosion monitoring methods based on ASTM methods.
