Experimental study on ice adhesion forces of the copper plates with specific contact angle and roughness

Abstract Experimental ice adhesion force measurements were conducted on the surfaces of the copper plates with specific contact angle and roughness. The ice adhesion forces formed by cooling the surfaces of the copper plates to different temperatures were compared and analyzed. The effect of frosting on the surfaces of the copper plates was eliminated, and the same cooling rate was adopted to strictly control the number of bubbles trapped in the ice and the formation conditions of fine cracks at the ice-copper interface. The duration of freezing was defined, and the changing law of the recalescence point and the duration of freezing was explored. The results show that the ice adhesion forces measured on the surfaces of the copper plates are larger when the target temperatures of the copper plates are −25 °C and −20 °C, while the ice adhesion forces measured at the target temperature of −10 °C are minimal. The experimental results with the target temperature of −25 °C are the most dispersed and covered the most extensive range. The maximum and minimum values of ice adhesion forces in this case are 11.28 N and 7.58 N, respectively, and the difference between them is 3.7 N.
