Abstract
Tantalum coating was obtained on the surface of Ti-50.6at%Ni shape memory alloy by multi-arc ion plating method. The depth profile was investigated by X-ray photoelectron spectroscopy (XPS): it was found that a uniform tantalum coating was formed on the TiNi alloy with little interfere between TiNi substrate and tantalum coating. The surface chemical composition and chemical state of the tantalum coating were also investigated XPS survey and high resolution spectra. A thin oxide film with Ta2O5 in the outmost layer and tantalum suboxides in the inner layer, were formed on the surface of tantalum coating as a result of natural oxidation of Ta in atmosphere.
