“…J. H. Jeong et al described "soft crystalline phase" as the decreased hardness of carbon layer due to small composition changes of crystallized carbon allotropes, such as graphite and CNTs. 32) On the contrary, the friction coefficients of both CDC films were not increased significantly at 1200°C because the friction coefficient was mainly determined by the surface termination states of the films 36) and both CDC films had the same covalent ·-bond states at the surface in those temperature ranges. Hence, the Fe-catalyzed CDC films show good friction coefficients between 0.1 and 0.15, and adding a metal catalyst at an adequate synthesis temperature can improve the wear rate of CDC films.…”

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.

“…Despite the characteristics of low friction and high wear resistance, the tribological properties of CDC coatings should be improved to use under extreme conditions [7][8][9][10][11][12]. Carroll et al demonstrated that CDC coatings with an onion-like structure exhibited low friction in dry nitrogen [10].…”

“…Given the wide range of structures that can be formed from carbon, from graphite to diamond, potential applications for carbon-based materials are nearly unlimited [1][2][3][4]. A microporous carbon structure, one of the many nanostructures that carbon can form, can be used for applications that range from purification to tribological applications to catalytic purposes.…”

“…The structure of the CDC produced is not homogeneous, but rather the structure is a heterogeneous mixture of imbedded graphite, diamond, carbon onions, amorphous carbon, and carbon nanotubes. The presence of the various structures within the CDC gives the material very interesting properties: significantly lower friction coefficient compared to the metal carbide, a very high specific surface area, and a hardness of 1-30 GPa [4,6].…”

Water Vapor Absorption on Nanostructured Carbide Derived Carbon (CDC)

The potential applications for carbide derived carbon has attracted a great deal of attention. In this work, CDC layers were synthesized on SiC and kept isolated from the environment until exposed to controlled water vapor atmospheres, so that the effects of water vapor pressure on the absorption could be quantified. The effects of high temperature hydrogen treatment on the water vapor absorption are also described. CDC samples, after a chlorination treatment are very hygroscopic, absorbing up to 35% of their weight in water in low humidity environments. The water absorption curves follow a type I IUPAC adsorption curve. However the sample, initially treated at 1000 C, after a hydrogen treatment, follows a type IV and can adsorb up to 100% of its mass in water vapor. The hydrogen treated isotherm suggests that the surface chemistry and structure of the CDC now has been altered.
