The Study of the Strength of Adhesion Contact of Ice on Surfaces with Different Wettabilities

A new approach to studying the strength of an adhesion contact is presented. This approach provides statistically reliable results and is based on the measurement of centrifugal force that causes a shear of ice on a solid surface. The developed experimental setup is employed to study the effects of environmental temperature and duration of ice incubation after crystallization on the measured adhesion strength for samples with different wettabilities. A noticeable temperature dependence is revealed for the shear strength of the adhesion contact between ice and solid surfaces of hydrophilic, hydrophobic, and superhydrophobic samples of an aluminum alloy. At the same time, substantially lower shear strength values of adhesion is observed for superhydrophobic surfaces, with these values decreasing with an increase in ice relaxation time.
