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
