Partial-Vacuum-Gasketed Electrochemical Corrosion Cell

An electrochemical cell for making corrosion measurements has been designed to prevent or reduce crevice corrosion, which is a common source of error in prior such cells. In a typical prior corrosion cell, crevice corrosion occurs at an interface between a material specimen, an electrolyte, and a specimen- mounting fixture. Crevice corrosion significantly alters current and voltage responses, thereby generating errors in the determination of both the thermodynamic and kinetic aspects of corrosion.
