The researchers start with a silicon carbide wafer. Using a process they developed themselves, they first convert its surface into a single-atomic layer of graphene. “If we vaporise sublimated gold on to this silicon carbide-graphene arrangement in a high vacuum, the gold atoms migrate between the carbide and the graphene”, explains Forti.
What is Tungsten Carbide or Hard Metal?
Tungsten Carbide is often referred to as a Hard Metal due to it’s very high hardness in relation to other metals. Tungsten Carbide is actually a composite material with hard particles of Tungsten Carbide eedded in a softer matrix of metallic Cobalt.

Tungsten carbide | chemical compound | Britannica
Tungsten carbide is a dense, metallike substance, light gray with a bluish tinge, that decomposes, rather than melts, at 2,600 C (4,700 F). It is prepared by heating powdered tungsten with carbon black in the presence of hydrogen at 1,400 –1,600 C (2,550 –2,900 F).
