Abstract
A surface layer of a material containing carbon and/or a carbide is produced on the outer surface of a solid carbon-based substrate (1) by selective application of material, said surface layer adhering strongly to the substrate, having a high specific surface area and having open pores (5) of a depth of at least 1 nm, and a metal material having a strong affinity for carbon, comprising at least one metal chosen from cerium, cobalt, chromium, iron, hafnium, iridium, osmium, palladium, platinum, rhodium, ruthenium, lanthanum, manganese, molybdenum, nickel, silicon, tantalum, thorium, titanium, uranium and tungsten, is deposited on said surface layer, substantially filling said pores. The metal deposit (8) may be rectified and polished without peeling off, in order to produce a mirror of low inertia.
