The study of the kinetics of water spreading on solid phases of carbon allotropic materials

Abstract

Kinetics of water spreading on the surface of solid phases of various carbon materials has been first studied with the use of high-speed video filming (up to 1200 frames per second). It has been found that rates of low-temperature liquid and metal melts spreading and wetting the surface of solid phases are close in time (the process length is 10−2–10−3s) and in both the cases the spreading occurs in an inert mode. It has been shown that at the final stages the spreading of low-temperature liquids occurs at a viscous mode (10–30 min) caused by the presence of an adsorbed layer (coat) on the solid phase surface due to the environment.
