“…Reactive dc-magnetron sputtering was the technique used for deposition from a pure Ti target with a power density of 1.7 W.cm -2 . A mixture of gases Ar + CH 4 was employed with different (Ar/CH 4 ) gas flows: 170/50, 190/30, and 210/10 sccm, maintaining the total flow at 220 sccm. All coatings were deposited with a constant applied substrate bias voltage of -300 V. Titanium inter-layers were deposited to improve the film adhesion on the metallic substrates.…”

“…In fact, the properties of carbon-based films are mostly influenced by the content and how C sp 2 and sp 3 hybridizations are arranged, as well as the amount of H into amorphous-carbon matrix 2 . Additionally, some foreign elements (for example, Ti, Si, O and F) are frequently incorporated into the amorphous matrix in order to tailor the properties of the coatings [2][3][4] . Hence a considerable variety of carbon-based films can be produced as far as the nano/micro-structure, chemical composition, optical, mechanical and tribological properties are concerned.…”

Ti-doped carbon coatings were deposited on TiAlV alloys by reactive dc-magnetron sputtering in Ar/CH 4 mixed gas. When Ar flow increases the incorporation of Ti into films raises while the concentration of C decreases. The formed nanometric TiC crystals were more noticeable for coatings deposited with higher Ar flows. Hardness (H) and elastic modulus (E) of coatings were measured by nanoindentation. H values were in the range of 8.8-15.9 GPa and E of 53.4-113.7 GPa. Higher values for H and E were obtained for films containing larger amount of TiC-phase. The presence of TiC crystals increased the coefficient of friction (COF) from 0.07 to 0.28 in scratch tests. Tribological experiments were carried out by using a pin-on-disk apparatus in air and in liquid. COF values ranged from 0.10 to 0.50 for tests in air. Despite of presenting higher COF, tests performed in liquid resulted in less pronounced wear tracks.

Diamond-like Nanocomposites (DLN) is a newly member in amorphous carbon (a:C) family. It consists of two or more interpenetrated atomic scale network structure. The amorphous silicon oxide (a:SiO) is incorporated within diamond-like carbon (DLC) matrix i.e. a:CH and both the network is interpenetrated by Si-C bond. Hence, the internal stress of deposited DLN film decreases remarkably compare to DLC. The diamond like properties has come due to

“…Diamond-like carbon (DLC) layers have potential applications in orthopaedics, cardiology, ophthalmology, nephrology, and other fields of medicine [1,[4][5][6][7][8][9]. DLC layers are ideal for coating stents, heart valves, because of its excellent haemocompatibility and reduced thrombus formation, and for joint implant protective films [10].…”

Abstract. Diamond like carbon (DLC) layers have excellent biological properties for use in medicine for coating implants, but poor adhesion to biomedical alloys (titanium alloys, chromium alloys and stainless steel). The adhesion can be improved by doping the DLC layer by chromium, as described in this article. Chromium doped diamond like carbon layers (Cr DLC) were deposited by hybrid deposition system using KrF excimer laser (deposition diamond like carbon -graphite target) and magnetron sputtering (deposition chromium -chromium target). Carbon and chromium contents were determined by wavelength dispersive X-ray spectroscopy. Chromium content of Cr DLC layers was 0, 1, 2, 4-5 and 15 17 at.%. The topology and roughness of layers were studied using atomic force microscopy. Roughness of chromium doped DLC layers was measured on Si substrates about 0.2-0.7 nm and on metallic substrates about 1-6 nm. Mechanical properties were studied by nanoindentation. Hardness and reduced Young s modulus were reduced with rising the Cr content. Hardness and reduced Young s modulus reached from 15.0 GPa to 31.2 GPa and from 172.7 to 271.5 GPa, respectively. Films adhesion was determined by scratch test and reached 19 N for titanium substrates and for highest Cr concentration. Good adhesion to biomedical alloys and high DLC hardness will help to progress in the field of implantology.
