Abstract: Experiments pertaining to ice formation on different materials, viz, metals, wood, plastics, concrete, and frozen soils have been carried out and the thermo-dynamics of icing process examined. The presence of an ice contact layer formed under the influence of the substratum material is established by means of crystallo-optical research. Adhesion strength is considered arguing from the hypothesis of a quasi-liquid transition layer. “Plane adhesion” and “Volumetric adhesion” are defined. The correlation is discussed between adhesion strength and ice structure and phase composition on the one hand, and temperature and substratum material on the other. It is revealed that the adhesion strength of freshwater ice grows with an increase in crystal dimensions, while that of saline ice decreases. The main requirements for the methods for determining adhesion strength are discussed.
