AB  - The aim of this work is to investigate the surface characteristics and corrosion 
      behavior of NiTi (50.6 at.% Ni) shape memory alloy coated by a ceramic-like and 
      highly biocompatible material, iridium oxide (IrO2). IrO2 coatings were prepared 
      by thermal decomposition of H2IrCl6 . 6H2O precursor solution at the temperature 
      of 300  degrees C, 400  degrees C and 500  degrees C, respectively. The surface morphology and 
      microstructure of the coatings were investigated by scanning electron microscope 
      (SEM) and glancing angle X-ray diffraction (GAXRD). X-ray photoelectron 
      spectroscopy (XPS) was employed to determine the surface elemental composition. 
      Corrosion resistance property of the coated samples was studied in a simulated 
      body fluid at 37+/-1  degrees C by electrochemical method. It was found that the morphology 
      and microstructure of the coatings were closely related to the oxidizing 
      temperatures. A relatively smooth, intact and amorphous coating was obtained when 
      the H2IrCl6.6H2O precursor solution (0.03 mol/L) was thermally decomposed at 300 
       degrees C for 0.5 h. Compared with the bare NiTi alloy, IrO2 coated samples exhibited 
      better corrosion resistance behavior to some extent.
