<P>PROBLEM TO BE SOLVED: To provide an erosion resistant anti-icing coating to be used on various components. <P>SOLUTION: Liquid and/or solid anti-icing fillers and/or oils are combined with erosion resistant silicone and/or fluorocarbon elastomeric materials to create erosion resistant anti-icing coatings. These coatings may be utilized to prevent ice build-up on various gas turbine engine components, aircraft components, watercrafts (i.e., boats and ships), power lines, telecommunication lines, etc. Each coated pin 10 was positioned in a test apparatus 20, where a layer of ice 30 was then grown on each coated pin 10 in the annular gap between the coated pin 10 and the mold 40. Thereafter, the ice adhesion strength on each coated pin 10 was determined quantitatively via a pin shear test. The pin shear test involved constraining the mold at its base 42 while the pin was loaded axially in the direction of arrow A. This puts the ice 30 into shear, and allows the load at which the ice de-bonded from each coated pin 10 to be determined. <P>COPYRIGHT: (C)2007,JPO&INPIT |
