Solid-Ice Interface Fracture and Controlling Methods

Ice accumulation on material surfaces can cause serious adverse effects on daily production and life. The study of solid-ice interface is one of the important research directions to solve the problem of ice accumulation on material surfaces. This chapter introduces the fracture mechanism of the solid-ice interface of different anti/deicing coatings and the failure mechanism of the solid-ice interface based on fracture mechanics. The prefabrication mechanism of microcracks at the solid-ice interface has also been shown. Due to the increase in icing area, the failure mechanism of the solid-ice interface is different. Through the analysis of the cohesion model and stress concentration theory, the low interface toughness coating shows an excellent effect on large-area de-icing. By exploring the influence factors of porosity, pore size, pore shape, and coating thickness on the fracture toughness of solid-ice interface, the control method is mastered, which lays a solid theoretical foundation for the engineering application of low-interface toughness coating.
