Title:
WEAR RESISTANT COATINGS TO REDUCE ICE ADHESION ON AIR FOILS
Document Type and Number:
WIPO Patent Application WO2004078873
Kind Code:
A3
Abstract:
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).
