Abstract: Decorative chromium demand in the worldwide market is more than three times of hard chromium. But chromium plating processes has long been known to hazardous. The corrosion resistance of a nano-crystalline Sn-Co-X alloy intended as an alternative for decorative chromium has been studied. The corrosion resistance of Sn-Co-X are all better than trivalent chromium, hexavalent chromium, and it is more better than coarser gained Sn-Co alloy. The microstructures of Sn-Co-X alloy were analyzed by SEM, TEM, XPS and AES. The mechanism of its excellent corrosion resistance is described.
