Our previous investigation has indicated that pure Ni, Fe and Cr
are all in active dissolution state at the corrosion potential [14].
Table 1 lists some electrochemical parameters obtained from the
potentiodynamic polarization curves of pure Ni, Fe and Cr in
molten (Li,Na,K)F at 700 8C [14]. The free corrosion current density
of Ni is 19.3 mA cm2 more than one order of magnitude lower
