文摘
- •
Metals Ni, Fe and Cr are all in active dissolution state in molten (Li,Na,K)F at 700 °C at the corrosion potential
- •
The introduction of 2% H2O in the corrosion environment significantly increases the corrosion current density of Ni, Fe and Cr.
- •
The addition of CrF3 only accelerates the dissolution of Cr and Fe.
- •
The diffusion coefficient of Cr3+ has been calculated to be 6.25 × 10−4 cm2 s−1.
