“…If the surface shows many chemically active sites and the covalent ·-bonds of the carbon atoms are unoccupied, the CDC layer may show a high friction coefficient; hence, adding hydrogen terminates the dangling bonds of carbon atoms at the surface thereby reducing the friction coefficient. 38) Therefore, the tribological properties such as the friction coefficients and wear rates for CDC layers can be enhanced by adding adequate hydrogen.…”

We reviewed the current research on carbide-derived carbon (CDC) for tribological applications. Carbon materials have been produced using CDC synthesis, in which the metallic components of carbides are selectively etched using high-temperature chlorination. The CDC materials show superior material properties for various applications. SiC is the most widely used carbide, so it was the main focus of the discussion. CDC films show various synthesis-parameter-dependent crystal structures, which affect the mechanical and electrical properties. We discussed the effects of CDC synthesis parameters including adding hydrogen, choosing an appropriate reaction temperature, using catalysts, and modifying the substrate surface with a gradient carbon layer on the structures and tribological properties of CDC layers. The reactions between chlorine gas and the metal components of carbides require the proper reaction temperature because the bonding strengths of carbide materials are unique. CDCsynthesized carbon materials show excellent mechanical and physical properties, which can be continuously enhanced by innovatively modifying various synthesis parameters and by combining CDC materials with other materials. Therefore, CDC materials show great potential for being used in a broader range of applications, and they may lead to new and extended applications for ceramic materials.

“…The formation and characterization of one-dimensional nanomaterials have attracted considerable attention because of their unique physical and chemical properties [1][2][3][4][5][6]. For example, they can be applied in organic light-emitting diodes (OLEDs), solid lubricants, DNA analysis, and electrochromic devices [7][8][9][10].…”

Carbide based ceramics are frequently used for the tribological applications, such as mechanical seals, owing to their good mechanical and chemical properties. Recently, studies of the tribological properties of these applications have become increasingly important due to the increasing need for severe operating conditions. In this study, the surface modification of carbide ceramics was attempted to improve the triblogical properties. Carbon layers were prepared on SiCTiC ceramics using a moderate and high temperature chlorination process. The microstructure and worn surfaces were analyzed by scanning electron microscopy and an ¡-step profilometer, respectively. Tribological tests were carried out on chlorinated SiCTiC surfaces using a ball on disc wear tester. Since carbon atoms in TiC were derived at lower temperatures than SiC, the distribution of carbon atoms within the modified layers were synthesized by the difference in reaction temperature and reaction time. The tribological properties were varied by the volume fraction of carbon and SiC in the modified layer. The friction coefficient and wear rate were decreased by controlling the structure and composition of the carbon based layer from 0.22 to 0.18 and 7.91 to 1.92 (©10 ¹6 mm 3 /N·m), respectively.
