Wear resistant coatings to reduce ice adhesion on air foils

摘要

A hard, wear resistant and ice-phobic coating ( 10 ) can be applied to an air foil surface ( 12 ) in a single application to enhance the deicing of the surface. The coating includes a functional top layer ( 14 ) which is harder than the air foil surface and has high contact angle with water. The functional layer contains carbon (>35 atomic %) and hydrogen (0-40 atomic %) in a diamond-like carbon, glassy, or amorphous configuration, as well as incorporated silicon and oxygen (0.1-40 atomic % each).
