Structural and mechanical properties of Ti-containing diamond-like carbon films deposited by filtered cathodic vacuum arc

Characterisation of Transfer Layer and Wear Debris on Various Counterparts Sliding Against Undoped and Doped DLC Coatings

“…Results from deconvolution of these spectra by Gaussian analysis show that they consist of D and G peaks, and the peak intensity ratio I D / I G for coatings differs significantly (Table 1). Referring to the results of previous investigations,21 the lowest value of the peak intensity ratio I D / I G for a DLC (0.6) coating shows a higher content of sp 3 bonds in it than in a TiC:H coating, where I D / I G = 1.2. It leads to higher hardness and higher elastic modulus of DLC than TiC:H coating.…”

Effect of bias voltage on microstructure and properties of Ti-doped graphite-like carbon films synthesized by magnetron sputtering

“…As seen from Fig. 5, the peak position of Ti2p was affected slightly as the bias voltage increases from 0 to −500 V. According to references [35,39], the strong peak at~455.0 eV in XPS spectra of Ti2p was assigned to Ti-C bonding. However, TiO may also attribute to the peak around 455 their close binding energy (455.1 eV for TiO [40]).…”

Diamond like carbon coatings for potential application in biological implants—a review

“…3 shows how silver can reduce the residual stress of the coating, with only a slight reduction in the hardness of the coating also reported. Titanium also reduces the residual stress by reducing the amount of sp 3 in the matrix, as well as improvements in the bonding between the substrate and the coating, further preventing delamination [20]. Titanium has also been shown to inhibit the growth of osteoclasts and other bone resorbing cells, improving the effectiveness of implants in situations where osseointegration is required [7].…”
