Anti-corrosion spraying treatment of wind turbine parts

       Anti-corrosion coatings on metal surfaces are mainly divided into two categories, namely metallic and non-metallic coatings.



Metal elements used for corrosion resistance are usually aluminum, zinc, chromium, and the like. In fan products, the common methods of steel structure parts are plasma spraying and flame spraying. The spray coating anti-corrosion method is mainly used on the surface of some refractory metals or large-area parts, and can also be used for the surface repair of parts. The electroplating method is to put the workpiece into the metal molten pool and pass the direct current, and the metal elements in the electrolyte are precipitated and deposited on the surface of the workpiece to form an electroplating layer. The electroplating method is also widely used in wind power products, such as auxiliary parts such as electrical assemblies, and the resulting electroplating layer has the advantages of wear resistance, corrosion resistance and aesthetics.

Wind power flanges are the key connecting parts, supports and stress-bearing parts of wind power towers. They are important components of wind power generation equipment and have very strict requirements for production. Because wind power flanges work in the external environment for a long time, they need to withstand Various severe weather and complex wind alternating loads are prone to corrosion and wear, affecting its normal operation. Jinan Tianmeng New Material Technology Co., Ltd. has thermally sprayed the surface of the wind power flange and sprayed the thermal sprayed aluminum coating, which has significantly improved the anti-corrosion and wear resistance, and greatly improved its service life.

The yaw system is one of the essential components of the horizontal axis wind turbine. The yaw system has two main functions. One is to cooperate with the control system of the wind turbine, so that the rotor of the wind turbine is always in the windward state, making full use of wind energy and improving the power generation efficiency of the wind turbine; the other is to provide Necessary locking torque to ensure the operation of the wind turbine. When a gear-driven yaw system is used, in order to avoid the oscillating wind direction change and causing alternating load on the yaw gear teeth, a yaw brake should be used to absorb the small free deflection oscillation and prevent the alternating stress of the yaw gear from causing the gear teeth premature injury. The yaw brake is vulnerable to wear during operation and needs to be maintained and repaired in time. wococarbide.com uses thermal spraying technology to spray metal coating on its surface. The metal coating prepared by thermal spraying technology has strong wear resistance and corrosion resistance, which can effectively enhance the strength of the substrate itself and enhance its service life
