Abstract
Official abstract text for this publication.
The present invention relates to rotor blades of devices, particularly of wind turbines, having an anti-ice coating, as well as to methods for their production and their use.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of coating a rotor blade to lower a freezing point of water on the rotor blade, the method comprising: lowering the freezing point of water on the rotor blade by coating at least one surface of the rotor blade with a coating selected from a group consisting of a first coating containing 15 to 75 atom-% fluorine and 25 to 85 atom-% further components (each determined according to XPS analysis) and a second coating containing 25 to 29 atom-% silicon, 22 to 45 atom-% oxygen, and 26 to 49 atom-% carbon (each determined according to XPS analysis), the coating having a structuring in a form of a dot pattern or a line pattern. 2. The method according to claim 1 , wherein the structuring in a form of a dot pattern or a line pattern has structuring in the micrometer range having dimensions of 1 to 1000 μm, and the coating further has a structuring in the nanometer range having dimensions of 0.02 to 40 nm. 3. The method according to claim 1 , wherein the coating has a thickness of 10 nm to 500 nm. 4. A rotor blade having a lowered freezing point comprising: a main body; and a coating lowering a freezing point of water on the main body of the rotor blade, the coating selected from a group consisting of a first coating containing 15 to 75 atom-% fluorine and 25 to 85 atom-% further components (each determined according to XPS analysis) and a second coating containing 25 to 29 atom-% silicon, 22 to 45 atom-% oxygen, and 26 to 49 atom-% carbon (each determined according to XPS analysis), wherein the coating is provided on at least one surface of the rotor blade and has a structuring in a form of a dot pattern or a line pattern. 5. The rotor blade according to claim 4 , wherein the structuring in a form of a dot pattern or a line pattern has structuring in the micrometer range having dimensions of 1 to 1000 μm, and the coating further has a structuring in the nanometer range having dimensions of 0.02 to 40 nm. 6. The rotor blade according to claim 4 , wherein the coating has a thickness of 10 nm to 500 nm. 7. A method of coating a rotor blade to lower a freezing point of water on the rotor blade, the method comprising: lowering the freezing point of water on the rotor blade by coating at least one surface of the rotor blade with a coating selected from a group consisting of a first coating containing 15 to 75 atom-% fluorine and 25 to 85 atom-% further components (each determined according to XPS analysis) and a second coating containing 25 to 29 atom-% silicon, 22 to 45 atom-% oxygen, and 26 to 49 atom-% carbon (each determined according to XPS analysis), the coating having a thickness of 10 nm to 500 nm, a first structuring in a form of a dot pattern or a line pattern having first structuring in the micrometer range having dimensions of 1 to 1000 μm, and a second structuring in the nanometer range having dimensions of 0.02 to 40 nm.
