“…Previous studies have observed the presence of a-C in TiC/a-C:H and (Ti,Cr)(C,N)/a-C at a C content below 20 at.% [25], [27]. This study did not observe an obvious a-C peak in the TaC that exhibited a C content of 43.6 at.%.…”

Tantalum (Ta) is a promising metal for biomedical implants or implant coating for orthopedic and dental applications because of its excellent corrosion resistance, fracture toughness, and biocompatibility. This study synthesizes biocompatible tantalum carbide (TaC) and TaC/amorphous carbon (a-C) coatings with different carbon contents by using a twin-gun magnetron sputtering system to improve their biological properties and explore potential surgical implant or device applications. The carbon content in the deposited coatings was regulated by controlling the magnetron power ratio of the pure graphite and Ta cathodes. The deposited TaC and TaC/a-C coatings exhibited better cell viability of human osteosarcoma cell line MG-63 than the uncoated Ti and Ta-coated samples. Inverted optical and confocal imaging was used to demonstrate the cell adhesion, distribution, and proliferation of each sample at different time points during the whole culture period. The results show that the TaC/a-C coating, which contained two metastable phases (TaC and a-C), was more biocompatible with MG-63 cells compared to the pure Ta coating. This suggests that the TaC/a-C coatings exhibit a better biocompatible performance for MG-63 cells, and they may improve implant osseointegration in clinics.

“…The responses of cell and tissues at implant interfaces have been shown to be affected by the chemical properties, topography, and roughness of the implant surfaces [10,11]. Thus, numerous surface treatment methods, such as sandblast, acid etching, discharge processing, sputtering coating, hydroxyapatite coating, and anodization, are employed to enhance the surface properties of the Ti metal at present [12][13][14][15][16][17][18]. The fatigue and fracture behavior are mostly improved by the modification of the microstructure via various surface treatments [19].…”

“…However, in an oral environment the mechanical properties of titanium may not be appropriate, as titanium possesses a high friction coefficient and low wear resistance [7,8]. Biocompatible candidates capable of meeting these requirements are the diamond-like carbon films (DLC), which present high hardness, low friction coefficient, high wear resistance besides bio and hemocompatibilities [6,[9][10][11][12][13][14][15]. Kim et al [6] studied the extent of abutment screw loosening of 1 lm thick DLC-coated and non-coated titanium dental implants.…”

Cell response and corrosion behavior of electrodeposited diamond-like carbon films on nanostructured titanium

et al. 2013

Surface characteristics such as roughness and contact angle of flat and nanostructured titanium samples and diamond-like carbon films (DLC) electrodeposited on the nanostructured samples were evaluated. Also, the mechanical properties and the corrosion resistance of the samples were evaluated in phosphate buffered saline (PBS). Biocompatibility was assessed by analyzing an in vitro cell culture. Nanostructured samples presented better cell biocompatibility. DLC deposited onto nanostructured samples remained with nanostructured morphology, presented high hardness and improved corrosion resistance compared to bare titanium. The DLC films electrodeposited from acetonitrile presented higher corrosion resistance in PBS solution when compared to DLC films deposited from N,N-dimethylformamide.
