摘要: 通过在试样表面制备不同疏水强度的涂层,在-8 ℃及-12 ℃温度下对静态冰和冲击冰2种成冰方式的切向结冰粘结强度进行测试,获得多个工况的切向结冰粘结强度。结果表明:随着温度的升高,无论是静态冰还是冲击冰,结冰粘结强度均呈下降趋势;静态结冰时,疏水性表面能有效降低结冰粘结强度,冲击结冰时,由于接触界面出现霜冰层,疏水性涂层对降低结冰粘结强度的效能较弱。

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.
