The multilayered TiN+Ti2N+aTi(N)/SiO2Ti-O2/hydroxyapatite system on Ti6A14VELI alloy

The paper presents the possibility of creating new biomaterials through designing bioceramic composite layers on titanium alloy by hybrid method. The TiN+Ti2N+aTi(N) and SiO2-TiO2 layers and finally, hydroxyapatite nano-film were deposited on Ti6A14VELI alloy. The suggested innovative hybrid method: glow-discharge nitriding in connection with other techniques such as sol-gel and electrophoresis and individual properties of each layers can play a significant role in designing the functional properties of medical implants. The preliminary studies indicated that multilayered system with TiN+Ti2N+aTi(N) layer are advantageous from the point of view of obtaining high quality and homogeneity of coatings. The modification of the surface of metal substrate - titanium alloy produced by hybrid method may be au effective way to improve bioactivity and consequently prolong the lifetime of implant.
