By calculation of chemical thermodynamics,we analysed some possible chemical reactions in netural vanadizing salt bath,and discovered that NaF doesn't participate in the reactions between the vanadizing source and reducing agent. The actual mechanism is that NaF reacted with the reaction product in the surface of reducing agent to clean the surface,thus the activity of the reducing agent was keeped,and the high concentration of the active V atoms in the salt bath was maintained.
