Surface treatment and coating technology evaluation of wind power spindle forging is an important part to ensure the performance and life of wind power spindle. Here’s an assessment of both:
- Surface treatment technology evaluation:
Surface treatment technology includes cleaning, rust removal, shot peening and polishing processes. The evaluation indicators mainly include the following points:
- Cleaning effect: The surface treatment process should be able to effectively remove impurities such as grease, dust, oxides on the surface of the forging to ensure the cleanliness of the surface.
- Rust removal effect: The rust removal process should completely remove the rust on the surface of the forging, ensuring that the surface is free of rust spots and rust marks.
- Shot peening effect: The shot peening process should be able to remove the oxide and hard skin on the surface of the forging without changing the size and shape of the forging, and enhance the surface roughness.
- Polishing effect: The polishing process should make the surface of the forging bright and smooth, and eliminate possible scratches and bumps.
- Coating technology evaluation:
Coating technology can be applied to the surface of wind power spindle forgings to improve its corrosion resistance, wear resistance and high temperature resistance. The evaluation indicators mainly include the following points:
- Comprehensive performance: The coating should have good corrosion resistance, wear resistance, high temperature resistance and fatigue resistance, and can protect the surface of the forging under harsh working environment.
- Binding force: The combination of the coating and the forging surface should be firm and not easy to flake or peel off.
- Thickness uniformity: The thickness of the coating should be uniform and meet the design requirements.
- Flatness: the surface of the coating should be smooth, and no defects such as roughness, depression, and bubbles are allowed.
It should be noted that the specific process and evaluation indicators for wind power spindle forging may vary, and the specific evaluation needs to be carried out according to the actual situation. Only general evaluation indicators are provided here.
