The wetting behavior of Au and Ag particles on a monocrystalline graphite substrate was investigated using the microscopic sessile drop method under a purified Ar atmosphere at 1300 K. The measured contact angles of the liquid Au and Ag on monocrystalline graphite substrates of (0001) face were 129° and 124°, respectively. It is believed that the interaction at the interface is dominated by the physical bonding (van der Waal's interaction).
