Wetting is the ability of a liquid to maintain contact with a solid surface, resulting from intermolecular interactions when the two are brought together. This happens in presence of a gaseous phase or another liquid phase not miscible with the first one. The degree of wetting (wettability) is determined by a force … See more Adhesive forces between a liquid and solid cause a liquid drop to spread across the surface. Cohesive forces within the liquid cause the drop to ball up and avoid contact with the surface. The See more Unlike ideal surfaces, real surfaces do not have perfect smoothness, rigidity, or chemical homogeneity. Such deviations from ideality result in phenomenon called contact angle hysteresis, which is defined as the difference between the advancing (θa) and receding … See more Surfactants Many technological processes require control of liquid spreading over solid surfaces. When a drop is placed on a surface, it can completely wet, partially wet, or not wet the surface. By reducing the surface tension … See more Liquids can interact with two main types of solid surfaces. Traditionally, solid surfaces have been divided into high-energy and … See more An ideal surface is flat, rigid, perfectly smooth, chemically homogeneous, and has zero contact angle hysteresis. Zero hysteresis implies the advancing and receding contact angles are equal. In other words, only one thermodynamically stable contact angle exists. … See more If a drop is placed on a smooth, horizontal surface, it is generally not in the equilibrium state. Hence, it spreads until an equilibrium contact radius is reached (partial wetting). While taking into account capillary, gravitational, and viscous contributions, the … See more • Adsorption – Phenomenon of surface adhesion • Amott test • Anti-fog – Chemicals that prevent the condensation of water as small droplets on a surface See more WebSep 1, 2013 · Predictive modeling of reactive wetting and metal joining.

WebReactive wetting caused by the gold plating is believed to be more effective than non-reactive wetting; e.g., the time required for wetting can be shortened to about 1/10 of that with no gold-plated surface. The author made various metallic-plated steels and tested them in sodium wetting experiments to study the effect of plating [ 3 ].
