1Nano-Structured Carbide-Derived Carbon Films and Their Tribology显示文摘Carbide-derived carbon (CDC) is a form of carbon produced by reacting metal carbides, such as SiC or TiC, with halogens at temperatures high enough to produce fast kinetics, but too low to permit the re- arrangement of the carbon atoms into an equilibrium graphitic structure. The structure of CDC is derivative of the original carbide structure and contains nanoscale porosity and both sp2 and sp3 bonded carbon in a variety of nanoscale structures. CDC can be produced as a thin film on hard carbides to improve their tri- bological performance. CDC coatings are distinguished by their low friction coefficients and high wear resis- tance in many important industrial environments and by their resistance to spallation and delamination. The tribology of CDC coatings on SiC surfaces is described in detail.Michael McNallan Daniel Ersoy Ranyi Zhu Allen Lee Christopher White Sascha Welz Yury Gogotsi Ali Erdemir Andriy Kovalchenko 2005Tsinghua Science and Technology2005,10,6:6
