Wang, R

The corrosion-resistant behavior of sputter-deposited amorphous and thermally crystallized Fe-Ni-Cr-W alloys was studied in chloride solutions using polarization methods. The amorphous alloys had excellent resistance to pitting in both neutral and acidic solutions. More significantly, the corrosion resistance of the alloys was preserved after heat treatment at the crystallization temperature. This was attributed to a two-stage crystallization process; thus, the amorphous matrix protects the alloy from corrosion of the crystallized phase.
