[0002] High-strength wind turbines are devices designed to operate stably in extreme climate and high-load environments. Such generators are usually installed in offshore or mountainous areas. Among them, bolts, as key structural components, need to have extremely high mechanical strength and corrosion resistance. These bolts not only need to withstand huge mechanical pressures but also resist harsh environmental factors such as salt spray, moisture, and temperature changes. Therefore, the requirements for the surface treatment of bolts are extremely high to ensure their long-term performance and safety.
