Abstract:

Cavitation occurring at the interface between a liquid and a solid is considered from the viewpoint of surface chemistry. The thermodynamics of the interface and the interfacial forces of attraction are reviewed. Emphasis is placed on those aspects that tend to suppress cavitation inception. Related past research is reviewed and evaluated using knowledge of the surface chemistry of the interface. It is concluded that cavitation inception can be suppressed by increasing the adhesion between the liquid and the solid and by reducing the amount of undissolved gas trapped on the solid surface.
