Compilation of erosion yields of metal-doped carbon materials by deuterium impact from ion beam and low temperature plasma

Abstract

The erosion yield by deuterium impact was determined for various doped carbon-based materials. Extensive carbide particle loss can be excluded up to fluences of ~10 25 m -2 .

Production of nanoTiC–graphite composites using Ti-doped self-sintering carbon mesophase powder

“…Unfortunately, properties such as thermal conductivity and resistance to erosion produced by energetic atoms of hydrogen and oxygen are not good enough to allow the implementation of the material in real conditions before these properties are improved. [1][2][3][4] The preparation of graphite composites reinforced with non-stoichiometric metal carbides such as TiC, ZrC, VC and WC 1,5,6 has been studied as a way to improve these properties. The improvement derives from two reasons 1,3,4,7-9 : (i) non-stoichiometric metallic carbides catalyse graphitisation, thus increasing the crystalline size of the graphite and, therefore, the thermal conductivity 1 properties of the metallic carbides (high thermal conductivity, high atomic number, etc.).…”
