Adhesive properties of ice. part II
Jellinek, H. H. G. (Hans Helmut Gunter), 1917-
Research ReportSummary: Adhesive strength of ice for the systems ice/stainless steel and ice/optically flat fused quartz has been investigated as a function of surface roughness of steel surfaces and rates of shear for steel and quartz. The adhesive strength decreases with decreasing roughness of steel surfaces and the force vs time curves for smooth steel plates resemble those of two solids sliding over each other with a liquid layer sandwiched between them. This is particularly so in the case of quartz. The adhesive strength as a function of rate of shear is linear both for ice/stainless steel and ice/quartz; however, there are indications of yield values. The experimental results are in agreement with the assumption of a liquidlike layer on ice. Ratios of viscosity coefficient to the thickness of the layer have been evaluated for both systems and viscosity coefficients are estimated. The importance of interfacial free energy considerations is pointed out.
