Fastener surface strengthening technology is an important technology to improve the surface performance of fasteners, and its application range is wide, including industrial production, daily use and other fields. This paper will introduce the development process, current situation and future development trend of fastener surface strengthening technology, and focus on its application prospect in actual production.
First, the basic principle of fastener surface strengthening technology
Fastener surface strengthening technology refers to improving the microstructure and performance of the fastener surface through physical, chemical or composite methods, so as to improve its wear resistance, fatigue resistance and corrosion resistance. These surface strengthening techniques include coating technology, ion implantation, laser hardening, shot peening, etc.
The coating technology is to coat the surface of the fastener with a layer of high hardness and high wear resistance to improve its wear resistance and fatigue resistance. Ion implantation is to inject elements with high wear resistance and high corrosion resistance into the surface of the fastener, thereby improving its corrosion resistance and wear resistance. Laser hardening and shot peening both produce a hardened layer on the surface of fasteners through strong mechanical action, thereby improving their wear resistance and fatigue resistance.
Second, the development and status of fastener surface strengthening technology
The research and development process of fastener surface strengthening technology has been more than a century, among which coating technology is the most widely used strengthening technology. In recent years, with the development of material science and surface engineering, new surface strengthening technologies have emerged, the most representative of which are laser hardening and shot peening.
At present, research institutions and expert teams at home and abroad are actively exploring new surface strengthening technologies. For example, a research team of a well-known domestic university has developed a new type of nanocomposite coating technology, which has the advantages of high hardness, high wear resistance, high corrosion resistance, etc., and can significantly improve the surface performance of fasteners. At the same time, a well-known foreign enterprise has developed a new type of ion implantation technology, which improves the surface performance of fasteners, but also has the advantages of environmental protection and energy saving.
Third, the application prospect of fastener surface strengthening technology
Fastener surface strengthening technology has a wide range of application prospects in industrial production, daily use and other fields. First of all, in industrial production, fasteners are indispensable parts in various mechanical equipment, and their performance directly affects the safety and service life of the equipment. The use of surface strengthening technology can improve the wear resistance, fatigue resistance and corrosion resistance of fasteners, so as to extend the service life of equipment and improve production efficiency. For example, in automotive manufacturing, the use of surface strengthening technology can improve the wear resistance and fatigue resistance of automotive fasteners, thereby improving the safety and service life of automobiles.
Secondly, in daily life, fasteners also have a wide range of applications. For example, in construction, various screws, nuts and other fasteners are indispensable parts in the building structure. The use of surface strengthening technology can improve the wear resistance and fatigue resistance of these fasteners, thereby extending the service life of the building. For example, in bridge construction, the use of surface strengthening technology can improve the fatigue resistance and wear resistance of bridge fasteners, so as to improve the safety and service life of Bridges.
In summary, the development and application of fastener surface strengthening technology has broad prospects and far-reaching significance. In the future, with the continuous development and progress of science and technology, it is believed that fastener surface strengthening technology will be applied and developed in more fields. At the same time, with the continuous improvement of product quality and performance requirements, the research and application of fastener surface strengthening technology will also receive more and more attention.
