“…The experimental results of shear adhesion strength studied by the authors and other scholars were also described in the graph. 27,31,35 It could be found that the range of variation of shear adhesion strength was significantly larger, with a difference of more than 15 times between the maximum and minimum values. On the one hand, various icing conditions results in differences in adhesion strength.…”

“…26 Memon used the same apparatus to investigate the effect of surface wettability and roughness on the normal adhesion strength. 27 Although there have been some studies on the normal ice adhesion, most of the research has focused on static ice that forms from stagnant water. In fact, the impact ice formed by supercooled water droplets hitting the wall during flight is very different from static ice.…”

Aircraft icing seriously jeopardizes flight safety. The design of aircraft anti-icing/de-icing systems requires a thorough understanding of the adhesion between the ice and the substrate. In this research, an experimental device that can be housed within a wing is designed and constructed. Simulation analysis of the interfacial stresses is performed, which reveals that increasing the load and the interface size led to a deterioration in the uniformity of stresses at the interface. In addition, the ice layer does not undergo cohesive damage during the tests. The normal ice adhesion strength is evaluated in an icing wind tunnel using the methodology outlined in this paper. Glaze ice exhibits an increase in normal adhesion strength at lower temperatures, whereas the trend is reversed for rime ice. The minimum adhesion strength occurs near the medium volume diameter (MVD) of 30 µm. Furthermore, the normal strength is significantly enhanced by increase in wind speed and surface roughness, as well as by surface painting. The adhesion strength of aluminum substrates to ice is greater compared to titanium and stainless steel. Compared to shear adhesion strength, normal adhesion strength is less sensitive to various influencing factors. The proposed experimental framework provides precise measurement of normal adhesion strength of impact ice in the icing wind tunnel.

“…The difference in heating duration indicates that there would be change in the overall initial ice adhesion force F at the ice/solid interface area; the residual adhesion force F 0 can be determined by Equation (). [ 47 ]

Unpredictable ice accretion and accumulation phenomena could lead to serious problems and even disastrous accidents. Applying icephobic coatings onto the engineering surfaces could be an effective ice protection method. The icephobicity could be mainly affected by several material strategies, such as wettability, surface topography and surface toughness, etc. In this work, several topographical surfaces (Ni‐Cu‐P coatings prepared on 304 stainless steel (SS) using electroless deposition) were critically investigated to understand the role of surface topography in affecting icephobic performances, including anti‐icing and de‐icing aspects. The freezing delay tests showed that rougher surfaces contribute to longer icing delay in anti‐icing. The ice adhesion strength results indicated that rougher surfaces led to more mechanical interlock ice and increased the ice adhesion strength between the ice‐solid interfaces. The electro‐thermal de‐icing tests indicated that the rough voids introduce large thermal resistance and impede the heat conduction, resulting in the increase in detachment duration and energy input in de‐icing. The rough asperity could introduce air pockets at the surface interfaces, which led to the difficulty of droplet phase transition. The rough structure also increased the mechanical interlock as well as the thermal resistance and impeded the heat conduction, which deteriorated the de‐icing ability.This article is protected by copyright.

It is still a big challenge to prepare superhydrophobic anti‐icing coatings with long freeze delay performance and high durability. In this work, in different with conventional flexible porous coating, we prepared an asymmetric coating with hierarchical pocket structure by a facile hot‐pressing/salt‐leaching (BHS) method on a polyacrylate vitrimer polymer with mellability. The asymmetric architecture endowed porous coating with low density and high adhesion strength. The in‐situ growth of silica nanoparticles in above porous coating and surface modification generated a superhydrophobic hierarchical pocket structure. As a result, the freezing delay time was drastically increased to 14,400 s at −10°C. Furthermore, owing to hierarchical pocket structure, the coating could maintain its superhydrophobicity and anti‐icing performance under water flow impacting at 10 kPa pressure, 30 cycles of sandpaper abrasion, 50 cycles of tape peeling, showing advantageous high durability. By employing the hierarchical porous coating on heat exchangers, the energy consumption was drastically reduced by 93%.
