SUMMARY:Icephobic Performance of Superhydrophobic Coatings - Ali Dolatabadi
  (Concordia)
DESCRIPTION:Icephobic Performance of Superhydrophobic CoatingsAli Dolatabad
 iDepartment of Mechanical and Industrial EngineeringConcordia University
\
 nAbstract: Suspension plasma spraying (SPS) technique has been used to dev
 elop microtextured TiO2 coatings with a hierarchical surface roughness to 
 develop superhydrophobic surfaces. Superhydrophobic coatings demonstrate e
 xtremely water repellent properties and can be potentially used for applic
 ations such as anti-icing\, reduced drag and friction\, self-cleaning and 
 corrosion resistance purposes. The focus of this presentation is on engine
 ering the hierarchical morphology or so-called “cauliflower” features 
 using a parametric study approach to optimize the wetting properties of th
 e 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 performa
 nce of superhydrophobic surfaces are assessed both experimentally and also
  through a detailed numerical modeling of cloud-sized droplet impact and s
 olidification.
