CORROSION BEHAVIOR OF Ni IN THE MOLTEN (Li ,K)2C03
Ni在熔融(Li,K)_2CO_3中的腐蚀行为

Electrochemical impedance spectrum technique was employed to study the cor- rosion behavior of Ni in the molten (Li,K)zC03 at 650'C. It is shown that the electrochemi- cal impedance spectrum for the corrosion of Ni have the characteristics of diffusion-controlled reaction. Ni suffers from fast corrosion, forming a porous oxide scale. A equivalent circuit representing the electrochemical impedance spectrum of Ni is proposed and the parameters in the equivalent circuit are also calculated.
