Fasteners are an indispensable part of the machinery manufacturing industry, and the heat treatment process in the manufacturing process is of great significance to improve the performance, hardness and corrosion resistance of fasteners. With the continuous development of science and technology, the research of fastener heat treatment process is also deepening. This paper aims to discuss the research and development status of fastener heat treatment technology, and look forward to the future development trend and prospect.
The research of heat treatment technology of fasteners mainly involves surface strengthening, residual stress, deformation and corrosion resistance. Surface strengthening is to improve the hardness, wear resistance and fatigue resistance of the fastener surface by heat treatment, such as surface carburizing, nitriding, ion implantation and other process methods. Residual stress research is mainly concerned with the generation, distribution and elimination of stress during heat treatment to avoid stress concentration leading to cracking or deformation of fasteners. Deformation research focuses on the flow and deformation of materials during heat treatment to control dimensional accuracy and stability of parts. Corrosion resistance research is aimed at the corrosion behavior of fasteners in the service environment and its influencing factors, aiming at improving the service life of fasteners.
With the continuous emergence of new materials and the growing demand for automation and intelligence in production, the future development trend and prospects of fastener heat treatment process are mainly reflected in the following aspects:
The application of new materials and technologies: such as the application of high-performance materials such as high-strength stainless steel, titanium alloy, aluminum alloy, will further improve the performance and service life of fasteners.
Implementation of intelligent and automated production lines: through the introduction of robots, automated control systems and intelligent testing equipment, the automation, continuity and intelligence of the production line are achieved, improving production efficiency and reducing production costs.
Green manufacturing and sustainable development: Pay attention to energy consumption, environmental pollution and other issues in the heat treatment process, develop green heat treatment technology, such as vacuum heat treatment, high frequency heat treatment, etc., to achieve sustainable development of manufacturing industry.
Interdisciplinary and cooperation: involving material science, physics, chemistry, mechanics and other fields, it is necessary to strengthen interdisciplinary and cooperation to promote the continuous innovation and development of fastener heat treatment technology.
The research and development of heat treatment technology of fasteners have made some achievements, and the surface strengthening, residual stress, deformation and corrosion resistance have been deeply discussed. However, there are also some shortcomings, such as insufficient research on the heat treatment process of new materials, intelligent and automated production lines have not been widely used, and the concept of green manufacturing and sustainable development still needs to be further promoted.
In order to further promote the development of fastener heat treatment process, it is necessary to pay attention to the following aspects:
In-depth research on the heat treatment process of new materials: For new high-strength stainless steel, titanium alloy, aluminum alloy and other high-performance materials, explore suitable heat treatment process methods to improve the performance and service life of fasteners.
Increase the promotion and application of intelligent and automated production lines: through the introduction of advanced robots, automated control systems and intelligent testing equipment, improve production efficiency, reduce production costs, and promote the automation, continuity and intelligence of production lines.
Strengthen the concept of green manufacturing and sustainable development: further pay attention to the energy consumption, environmental pollution and other issues in the heat treatment process, and actively develop green heat treatment technology, such as vacuum heat treatment, high-frequency heat treatment, etc., to achieve sustainable development of the manufacturing industry.
Strengthen interdisciplinary and cooperation: The cross-integration of materials science, physics, chemistry, mechanics and other fields will bring new opportunities for the development of fastener heat treatment technology, and promote the continuous innovation and development of technology through interdisciplinary cooperation.
