Icephobic Performance of Superhydrophobic Coatings
Department of Mechanical and Industrial Engineering
Abstract: Suspension plasma spraying (SPS) technique has been used to develop microtextured TiO2 coatings with a hierarchical surface roughness to develop superhydrophobic surfaces. Superhydrophobic coatings demonstrate extremely water repellent properties and can be potentially used for applications such as anti-icing, reduced drag and friction, self-cleaning and corrosion resistance purposes. The focus of this presentation is on engineering the hierarchical morphology or so-called “cauliflower” features using a parametric study approach to optimize the wetting properties of the coatings. It is demonstrated that by carefully designing and controlling the process parameters, rather fine and uniform dual-scale (hierarchical) surface textured coatings can be generated. Finally, icephobic performance of superhydrophobic surfaces are assessed both experimentally and also through a detailed numerical modeling of cloud-sized droplet impact and solidification.
