With the rapid development of wind power generation, as one of the core components of wind turbine, wind power spindle forging carries important functions and responsibilities. In order to improve the performance and life of wind power spindle forging, laser processing and surface modification technology has become an important means. This paper focuses on the laser processing and surface modification technology of wind power spindle forging.
First, laser processing technology:
- Laser drilling: Through the high energy density of the laser beam to wind power spindle forging holes, can make the aperture smooth, no residual stress, and can achieve high-speed, high-precision hole processing. Such a hole structure can improve the lubrication effect of lubricating oil and reduce energy loss.
- Laser cutting: The high energy coking characteristics of the laser beam are used to cut the wind power spindle forgings, which can achieve high-speed and high-precision cutting, and reduce deformation and residual stress in the cutting process. Laser cutting technology can improve cutting quality and efficiency, and reduce manufacturing costs.
- Laser welding: Laser welding technology can achieve high-strength and high-precision welding, avoiding the generation of heat-affected areas in the traditional welding process. For wind power spindle forging, the use of laser welding technology can improve the reliability and life of the product.
Second, surface modification technology:
- Surface strengthening treatment: Through surface modification methods such as laser cladding and laser alloying, a coating with higher strength and better wear resistance can be formed on the surface of the wind power spindle forgings to improve its fatigue resistance and corrosion resistance. At the same time, the material with higher hardness can also be dissolved on the substrate surface through laser surface alloying technology to further improve the wear resistance of the wind power spindle forging.
- Surface composite modification: Through the combined application of laser treatment and other surface modification technologies, such as laser etching, laser cladding, etc., a fine structure, nanoparticle and other composite layer can be formed on the surface of the wind power spindle forging, improving its surface performance and improving tribological characteristics.
- Surface coating technology: laser assisted thermal spraying, laser chemical vapor deposition and other technologies can form a coating with high adhesion and high density on the surface of the wind power spindle forging, improving its wear resistance, corrosion resistance, high temperature resistance and other properties.
Through laser processing and surface modification technology, the performance and life of wind power spindle forging can be effectively improved, and its reliability and use effect can be improved. These technologies have been widely used in aerospace, energy and other fields, and are constantly developing and improving. In the future, with the advancement and innovation of technology, laser processing and surface modification technology will bring more opportunities and challenges for the manufacturing and application of wind power spindle forgings.
