National Nano Device Laboratories, Hsinchu Received 17 October 2011; accepted 21 February 2012 Abstract: To improve the characteristics of a diamond-like carbon (DLC) film, Ti-containing amorphous......
, Materials Research Institute, Sheffield, United Kingdom;3.Hauzer Techno Coating, Venlo, Netherlands) 摘要:New carbon based coatings have been developed for cutting of light metals such as aluminum. These coatings can be used either directly on the tool or as topcoating combined with another hard base coating. Cutting tests show that the coating gives good performance for materials that tend to stick......
Article ID: 1003-6326(2005)05-1014-07 Preparation of composite electroheat carbon film XIA Jin-tong(夏金童), TU Chuan-jun(涂川俊), LI Yan(李 焰), HU Li-min(胡利明), DENG Jiu-hua(邓久华) (College..., was developed in view of the traditional electroheat coating which has a low surface electroheat temperature and an insufficient heat resistance of its binder. The coating molded electroheat carbon film......
J. Cent. South Univ. (2012) 19: 1780-1784 DOI: 10.1007/s11771-012-1207-y Microstructure and thermal conductivity of carbon/carbon composites made with different kinds of carbon fibers CHEN Jie(陈洁... Heidelberg 2012 Abstract: The microstructure and surface state of three kinds of polyacrylonitrile-based carbon fibers (T700, T300 and M40) before and after high temperature treatment were investigated......
composition of the steel changes by diffusion of carbon and or nitrogen and result in hard outer surface with good wear resistance properties. A striking feature of Gas Carburizing process.... In one condition it can be very mild, soft and suitable for any forming operation. In another condition the same steel can be very hard and strong. This versatility is made possible by the different......
