Abstract : Experiments by Smith-Johannsen on the adhesion of ice frozen from a number of 0.001 M electrolyte solutions to a wax-treated aluminum surface at -10C are discussed. It is concluded that the adhesive strength measured by the force per square centimeter needed to shear the ice off the substrate surface is mainly due to a liquid interfacial solution layer between the ice and the substrate surface. The thickness of such a layer is largely determined by the same considerations as the thickness of grain boundary layers in ice obtained from dilute electrolyte solutions. (Author)
