“…A popular method of obtaining better properties of the titanium alloys tested is coating them using silicates [19], chitosan [20,21], or phosphates including hydroxyapatite (HAp) [22][23][24][25] and nanoHAp [7,[26][27][28]-together with their composite combinations with other elements [26,[28][29][30][31][32][33]-thus facilitating better adhesion and antibacterial properties. Carbon and diamond-like coatings [34][35][36][37][38][39] and their composite combinations with other elements [40][41][42], as well as carbon nanotubes (CNTs) [41,[43][44][45] and their composite combinations with other elements [31,45,46] have been tested to obtain better mechanical (especially nanohardness) and anti-corrosive properties. The evolution of multi-walled carbon nanotubes (MWCNTs) for in situ TiC formation during spark-plasma sintering in titanium metal matrix composites allows significantly enhancing the mechanical and tribological properties of the composites [47].…”

Titanium and its alloys is the main group of materials used in prosthetics and implantology. Despite their popularity and many advantages associated with their biocompatibility, these materials have a few significant disadvantages. These include low biologic activity—which reduces the growth of fibrous tissue and allows loosening of the prosthesis—the possibility of metallosis and related inflammation or other allergic reactions, as well as abrasion of the material during operation. Searching for the best combinations of material properties for implants in today′s world is not only associated with research on new alloys, but primarily with the modification of their surface layers. The proposed laser modification of the Ti13Nb13Zr alloy with a carbon nanotube coating is aimed at eliminating most of the problems mentioned above. The carbon coating was carried out by electrophoretic deposition (EPD) onto ground and etched substrates. This form of carbon was used due to the confirmed biocompatibility with the human body and the ability to create titanium carbides after laser treatment. The EPD-deposited carbon nanotube coating was subjected to laser treatment. Due to high power densities applied to the material during laser treatment, non-equilibrium structures were observed while improving mechanical and anti-corrosive properties. An electrophoretically deposited coating of carbon nanotubes further improved the effects of laser processing through greater strengthening, hardness or Young′s modulus similar to that required, as well as led to an increase in corrosion resistance. The advantage of the presented laser modification of the Ti13Nb13Zr alloy with a carbon coating is the lack of surface cracks, which are difficult to eliminate with traditional laser treatment of Ti alloys. All samples tested showed contact angles between 46° and 82° and thus, based on the literature reports, they have hydrophilic surfaces suitable for cell adhesion.

“…The author recognized that the use of DLC deposited tools reduces feeding forces when Al-Si alloys are turned. Few researchers explored the performance of DLC coated cutting tools on different workpiece materials under various cutting operations and and it was observed a much reduced process of adhesion for the DLC layer over the substrates [3][4][5][6][7][8][9]. These authors found that during machining of aluminium alloys, Experimental assessment on machinability performance of CNT and DLC coated HSS tools for hard turning DLC films allows to avoid the adherence of aluminium on the tool surface, reduce cutting forces, increase the surface roughness and accuracy of the machined surface, facilitate the evacuation of chips and reduce the wear significantly.…”

“…At a high Ar/hydrocarbon ratio, because the bond dissociation energy of Ar is much smaller than hydrocarbon, the deposited films will extensively be bombarded by the large amount of Ar + . Meanwhile, at the low Ar/hydrocarbon ratio, it has been reported that the carbon can be ionized from hydrocarbon gases and then completely cover the Ti target which is called "target poisoning" [7,8]. In addition, according to the report [15], the low Ti-doped in amorphous carbon matrix could be surrounded by the Ti atoms or amorphous TiC rather than nanocrystalline TiC resulting in a high C-sp 2 .…”

“…Therefore, an interlayer/multilayer deposition has been proposed to obtain high-quality DLC film [5,6]. Here, the Ti film is one of the most effective interlayers with good capability and suitability for DLC coating [7,8]. It was reported that Ti-doped DLC coated on the steel could further improve the mechanical properties and corrosion resistance, resulting in a prolong shelf-life of steel products [9].…”

In this work, the successful preparation of the multilayer Titanium doped diamond-like carbon/Ti (Ti-DLC/Ti) films deposited on low-carbon steel (CS) using hybrid magnetron sputtering (MS) and plasma-enhanced chemical vapor deposition methods has been reported. The Ti and Ti-DLC films were alternately deposited on the CS substrate of up to 4 stacks with an average deposition rate of 16.4±1.7 nm/min and 15.1±1.5 nm/min, respectively, yielding a total thickness of up to 1703 nm. Raman spectroscopic analysis revealed a gradual increase in the I D/I G ratio with an increase in Ti layer numbers. Both XPS and NEXAFS results indicate an increase in the C-sp 2 content by increasing the number of Ti layer, which may influence on the hardness reduction. The adhesive properties were found to be improved by adding the number of Ti interlayers between the CS substrate. Moreover, the thicker multilayer films exhibit progressive homogeneity resulting in better corrosion resistance.
