Surface Phosphating of Amorphous Fe-W Deposit and Its Corrosion Behavior in NaCl Solution
Abstract:
A fine phosphate coating was fo rmed on the surface of amorphous Fe-W deposit after phosphating in zincous phosphating solution. The anodic polarization curves show ed that the pitting potential of Fe-W deposit moves about 1.4 V tow ard noble after phosphating. The immersion test showed that the corrosion resistance of Fe-W deposit against Cl- after phosphating has increased and its corrosion rate is about one fifth of that of the original FeW deposit.
