Kinetics of high-temperature spreading

Spreading of Viscous Liquids at High Temperature: Silicate Glasseson Molybdenum

Lopez-Esteban, Sonia ; Saiz, Eduardo ; Moya, Jose S. ; ... December 2004 - Langmuir

The spreading of Si-Ca-Al-Ti-O glasses on molybdenum has been investigated. By controlling the oxygen activity in the furnace, spreading can take place under reactive or non-reactive conditions. As the nucleation of the reaction product under reactive conditions is slow in comparison to the spreading kinetics, in both cases the glass front moves on the metal surface with similar spreading velocities. Spreading can be described using a molecular dynamics model where the main contribution to the wetting activation energy comes from the viscous interactions in the liquid. Enhanced interfacial diffusions in low-oxygen activities (reactive cases) form triple-line ridges that can pinmore »« less

Dynamic contact angles in mercury/carbon tetrachloride/solution systems. Pt. 1. Factors affecting spreading. Pt. 2. The process of attachment. Pt. 3. The mechanism and kinetics of spreading

Wilkinson, M.C. ; Elliott, T.A. August 1974 - J. Colloid Interface Sci.; (United States)

Although a great deal of experimental work is available in the literature on studies of static (equilibrium) contact angles, relatively little has been done on the dynamic aspects of the contact angle during spreading. Two distinctly different types of spreading are found: self spreading and force spreading. In both cases the contact angle changes with time, and is termed the dynamic contact angle. The impact, process of attachment, and subsequent spreading of drops of carbon tetrachloride at mercury/solution interfaces were recorded photographically. The effect of the history of the drop, prior to attachment at the interface, on the subsequent spreadingmore »« less

Kinetics of diffusion-limited spreading of sessile drops in reactive wetting

Mortensen, A. ; Drevet, B. ; Eustathopoulos, N. March 1997 - Scripta Materialia

Recent sessile drop experiments on metal/ceramic systems have shown that a sufficient condition for improving wetting of a given substrate by a given metal is to alloy the metal with a chemical species which reacts with the substrate to form a dense layer of solid reaction product that is better wetted by the metal than the original solid substrate. Such use of chemical reactions between liquid and substrate to promote wetting is frequent, and generally causes transitions with time in the wetting angle that is measured during a sessile drop experiment. The authors examine in this article the case wheremore »« less
