Low-pressure impulse vacuum heat treatment is a new technology developed in recent years, which has been applied in the fields of aircraft industry, automobile industry, electronics industry and other high-end products. This new technology can effectively improve the fatigue strength, wear resistance and corrosion resistance of products, which is beneficial to improve the products service life and performance.
The low-pressure impulse vacuum heat treatment technology combines the advantages of following two technologies: conventional vacuum heat treatment technology and high pressure water vapor heat treatment technology. It can reduce the cost of product processing to a certain extent, and it also respects the low carbon production requirements of the times. Low-pressure impulse vacuum heat treatment is an efficient way to improve the performance of metal material, which can effectively control the disordering degree of atomic arrangement, reduce the size of internal stress and improve the surface finish of products.
The low-pressure impulse vacuum heat treatment is divided into three stages, namely heating-holding-cooling. During the high-voltage pulse vacuum furnace, it is necessary to control the surface of the sample and the internal temperature at all times. The low-pressure pulse heating can achieve the uniform heating of all materials, and the surrounding air pressure is strictly controlled. During the cooling process, the heat can be evenly and quickly transferred from the center of the material, so that it can be cooled within a short time and evenly, and the high temperature distortion caused by uneven heat is also avoided.
The low-pressure pulse vacuum heat treatment has improved the strength, uniformity, corrosion resistance and wear resistance of many metal materials. Therefore, it is widely used in various fields such as automobile, aerospace, electronics, instrumentation and other fields. It can not only effectively improve the performance and quality of parts, but also increase the service life of parts. In addition, the low-pressure pulse vacuum heat treatment technology can also bring savings in cost.
In conclusion, low-pressure impulse vacuum heat treatment technology is an efficient and environmentally-friendly heat treatment technology developed in recent years. It can improve the performance of metal materials and reduce the cost of product processing at the same time. It is widely used in various fields. At the same time, it has also achieved remarkable results in extending the service life of metals and promoting the development of various industries.
