The main uses of nickel protective covers for carbon fiber propellers are as follows:

1. Enhance wear resistance

Nickel has high hardness and good wear resistance. Using nickel protective covers on the surface of carbon fiber propellers can effectively prevent direct friction between the propeller and external objects during operation, which can cause wear and tear. For example, in some multi rotor drone application scenarios, the propeller may experience slight collisions or friction with surrounding debris, tree branches, etc. The nickel protective cover can withstand these frictions, protect the internal carbon fiber structure, and greatly extend the service life of the propeller.

2. Improve corrosion resistance

Nickel has certain corrosion resistance to many chemicals and can protect carbon fiber propellers under different environmental conditions. In humid air, environments with chemical pollution, or when in contact with corrosive liquids, nickel protective covers can act as a barrier to prevent moisture, chemicals, and other substances from directly contacting carbon fibers, preventing their performance from deteriorating due to corrosion. This is particularly important for aircraft propellers used in harsh conditions such as marine environments.

3. Improve surface smoothness

Nickel protective covers can have a very smooth surface after processing. A smooth surface helps reduce the resistance of air flowing on the surface of the propeller and improve its aerodynamic performance. When the propeller rotates at high speed, air can flow more smoothly over its surface, making the lift and thrust generated by the propeller more stable and efficient, thereby improving the overall flight performance of the aircraft.

4. Enhance structural strength

The nickel protective sleeve is tightly integrated with the carbon fiber propeller, which can enhance the structural strength of the propeller to a certain extent. When the propeller is subjected to external force impact or centrifugal force generated by high-speed rotation, the nickel protective sleeve can share some of the stress and bear the load together with the carbon fiber, improving the overall deformation and damage resistance of the propeller and ensuring its stable operation under complex working conditions.

5. Electromagnetic shielding effect (under specific circumstances)

In some application scenarios that require electromagnetic environment, nickel has certain electromagnetic shielding performance. The nickel protective sleeve of carbon fiber propeller can provide certain electromagnetic shielding effect, preventing electromagnetic interference generated by the propeller during high-speed rotation from affecting the electronic equipment on the aircraft, ensuring that the electronic system of the aircraft can work normally.
