Durable metal or metallic alloy based ice release coatings

摘要

Icephobic coatings that reduce ice adhesion strength must often achieve extreme durability requirements, such as in aviation or wind turbine applications, to survive the impact of high-speed rain (i.e., rain erosion testing). A multi-layer coating having a thin metallic or metallic alloy film adhered to an underlying layer that is softer and thicker than the metallic layer achieves very low ice adhesion with adhered ice onto the icephobic coating.
