EROSION OF SURFACE-COATINGS IN HYDRODYNAMIC FLOWS

This paper describes a preliminary study of the mechanisms of the remo val of surface coatings in hydrodynamic flows. The bulk cohesive and i nterfacial properties of model deposits were measured and experiments under liquid flows were also performed to investigate the effects of h ydrodynamic stresses on the deposits. Comparisons were made between th e erosion characteristics of deposits under hydrodynamic flows and the ir measured mechanical and interfacial properties.
