The effects of alloying additions on the wetting of two types of carbon, HX30 graphite and vitreous carbon, have been investigated, with a view to developing a system for metal impregnation of carbon fibre assemblies. Pure copper is inert and non-wetting but two additions caused the copper to wet: Cr on both substrates and V on the vitreous carbon only. Many of the additions formed a carbide reaction layer at the interface, and in the two wetting systems this was a thin, continuous, coherent layer. The data have been analysed in terms of the chemical and physical properties of the system and it was found that the wetting behaviour of copper alloys on HX30 graphite and vitreous carbon could be explained in terms of the behaviour of the reaction product carbides of the alloying addition when these existed.read more

Dynamics of wetting in reactive metal/ ceramic systems
TL;DR: In this article, the driving force of reactive wetting and the crucial question of the final contact angle in a reactive system were investigated. But the authors focused mainly on the following two questions: (i) the origin of this force and (ii) different processes which can be rate-limiting, namely the viscous flow, the diffusion within the drop and chemical kinetics at the triple line.
