“…Hitherto, a type of the most studied carbon-based nanocomposite can be fabricated by the doping of strong-carbide-forming (SCF) metal such as W, Ti or Cr and so on, where the metal can bond strongly with carbon to form carbide nanocrystallites in the a-C matrix. [18][19][20][21] For instance, W-doped carbon-based nanocomposite coatings, which formed WC carbide phase in the a-C matrix, have been widely investigated in recent years. Moreover, the hardness, toughness, friction and wear-resistance of these coatings can be tuned to a certain extent by changing the composition and thereby the microstructure of the coatings.…”

Friction has a direct relation with the energy efficiency and environmental cleanliness in all moving mechanical systems. To develop low friction coatings is extremely beneficial for preserving not only our limited energy resources but also the earth's environment. This study proposes a new design for low friction carbon-based nanocomposite coatings by tailoring the microstructure and phase segregation, and thereby it contributes to better controlling the mechanical and tribological properties. Experimental findings and theoretical calculations reveal that high-hardness (18.2 GPa), high-adhesion strength (28 N) as well as low-internal stress (À0.8 GPa) can be achieved by a nanocrystallite/ amorphous microstructure architecture for the nc-WC/a-C(Al) carbon-based nanocomposite coating; in particular low friction ($0.05) can be acquired by creating a strong thermodynamic driving force to promote phase segregation of graphitic carbon from the a-C structure so as to form a low shear strength graphitic tribo-layer on the friction contact surfaces. This design concept is general and has been successfully employed to fabricate a wide class of low friction carbon-based nanocomposite coatings.

“…9) Previous studies also have shown that TiC x N 1¹x film presents low-friction behavior, similar to other carbon-containing materials. 4),10) However, the tribology of titanium carbonitride films is not yet completely understood due to the complexity of the system and the tribo-mechanism themselves. Many researchers have been studied these issues.…”

The effects of carbon content on the tribological behavior of titanium carbonitride(TiC x N 1¹x ) films have been studied herein. A set of titanium carbonitride(TiC x N 1¹x ) films was prepared by arc ion plating with a pure Ti target and a gas mixture of C 2 H 2 /N 2 on a steel substrate. High-definition field-emission scanning electron microscopy (FESEM) was used to investigate the microstructure of the films. The chemical composition of the films was analyzed using both electron dispersion spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS) analysis. The surface roughness and microhardness of the films were measured using ¡-step profilometer and nanoindenter respectively. The tribology of titanium carbonitride(TiC x N 1¹x ) films was investigated using a ballon-disc testing method and the wear tracks were observed by low-magnification SEM. The tribological behavior of the films was significantly changed with variation of the C 2 H 2 /N 2 gas ratio. A very low friction coefficient (0.07) of titanium carbonitride(TiC x N 1¹x ) film was observed when the C 2 H 2 :N 2 gas ratio was about 3:2.
