Abstract
This chapter presents the accelerating corrosion test method with various operating apparatus designed by ASTM standard guide. It is used to measure the corrosion resistance of coated and painted samples. The important uses of electrochemical techniques are linear polarization, potentiodynamic polarization, and electrochemical impedance spectroscopy. These are discussed in measuring the corrosion rate for coated and painted specimens.
Keywords: Corrosion, Electrochemical Cell, Electrochemical Impedance Spectroscopy, Salt Fog Test.
