摘要：

The corrosion properties of TiNi alloys coated with tantalum were determined and were compared with the uncoated samples by electrochemical measurements. Multi-arc ion plating technique was used to coat TiNi shape memory alloys with tantalum. Higher open-circuit potential, lower pitting potential, passive current density, and a smaller hysteresis area were observed for the coated TiNi sample. These observations demonstrated that the technique of multi-arc ion plating improved the corrosion property and could be used to coat TiNi alloy.
