NiTi alloys are frequently used in medical applications as a material for implants. The high risk of toxicity, caused by diffusion of nickel ions to the human body, requires developing a technology for deposition of a protective layer. Due to the unique physical and chemical properties the carbon-based layers are one of the possibilities for a surface protection. The carbon layer was deposited on Ni(50.6at%)Ti shape memory alloy using the RFPECVD process. The layers were studied using a wide range of methods. The structure was investigated using a high resolution electron microscope, greasing incident X-ray diffraction and reflectometry. The Auger spectrometer was applied for chemical analyses. Results reveal that the structure of carbon layer consists of nanocrystaline diamond particles in amorphous and/or nano-graphitic matrix. Basing on the Auger spectroscopy it was stated that the layers posses DLC qualities. The layers, deposited in this process, have a good quality and high corrosion resistance.
