IntroductionAccelerated methods for determining the efficacy of organic barrier coatings on metal surfaces have been of interest for many years.

IntroductionA quite popular experiment performed with Gamry Instruments’ potentiostats is the Potentiodynamic Scan and its sibling, Cyclic Polarization. These experiments are often used to study corrosion at a surface.

Review of the Electrochemical Basis of CorrosionMost metallic corrosion occurs via electrochemical reactions at the interface between the metal and an electrolyte solution.

A Lunch-Time DemonstrationWe were recently bringing some new engineering and production employees up-to-speed on electrochemistry, since they had never seen an electrochemical cell in action.

IntroductionThe Rapid Electrochemical Assessment of Paint (REAP) is a procedure designed to estimate the long-term corrosion resistance of coated metals using short term electrochemical tests.

Overview of Polarization ResistanceLinear polarization resistance (LPR) is a quick, nondestructive testing technique commonly used in material corrosion studies to gain corrosion rate data.

IntroductionLocalized corrosion, including crevice corrosion, is a leading cause of corrosion-induced failures. THE Method (Tsujikawa-Hisamatsu-Electrochemical Method) has been proposed to measure crevice corrosion repassivation potentials.
