Abstract

Surface icing brings many problems in the field of energy and electric power. Reducing the bonding strength of icing by constructing a hydrophobic coating on the substrate surface is a research hotspot at this stage. In this paper, the coatings with different hydrophobic strength were prepared on the surface of the sample. The tangential ice bonding strength of static ice and impact ice was tested at-8 ℃ and-12 ℃, and the tangential ice bonding strength under multiple working conditions was obtained. The test results show that with the increase of temperature, the bond strength of ice has a downward trend both in static ice and impact ice. When static icing, hydrophobic surface can effectively reduce the bonding strength of icing. When impact icing, due to the appearance of frost ice layer at the contact interface, hydrophobic coating has weak effect on reducing the bonding strength of icing.
