Title:
CARBON MATERIAL AND PROCESS FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2012/032858
Kind Code:
A1
Abstract:
A carbon material is provided in which a layer of a metal having high reactivity with carbon, such as tungsten, was able to be formed over a carbon base while inhibiting a steep rise in production cost or a decrease in processing accuracy. Also provided is a process for producing the carbon material. The carbon material is characterized in that a first layer (12) comprising a carbide of a transition metal and a second layer (13) have been formed in this order on the surface of a carbon base (2), the second layer (13) comprising at least one second metal selected from among the metals belonging to Groups 4, 5, and 6 and/or carbides of the second metal and of the transition metal.
