...) and electrochemical impedance spectroscopy (EIS), in which the impedance curves were fitted using ZSimDem software with the appropriate equivalent circuit. The PPCs were measured at the voltage scanning rate of 1 mV/s, the range from −300 to +300 mV and the sensibility of 0.01 A/V. All the tests were repeated three...

... polarization curve (PPC) and electrochemical impedance spectroscopy (EIS) tests. Findings The OCP and PPC of WC–12Co coating positively shift than those of substrate, its corrosion tendency and corrosion rate decrease to enhance its corrosion resistance. The curvature radius of capacitance curve on the WC...
