---

With the continuous development of material science and engineering technology, vacuum sintering technology has been widely used in the field of material preparation and heat treatment.

1.Working principle of vacuum sintering

Vacuum sintering is a process for sintering shapes (finished and semi-finished) for powdery and bulk materials. The basic process is to place the sintered material in the vacuum furnace, close the furnace door to vacuumize the furnace, and pump the vacuum to the required working vacuum (generally 3×10^-3 Pa). Then inflate immediately to complete the whole process of sintering.

2.Characteristics of vacuum sintering

Vacuum sintering process: powdery materials are mixed and pressed into various required shapes, and the pressed billets are put into a vacuum sintering furnace. Close the furnace door and evacuate until the vacuum degree reaches the required working vacuum degree (generally 2 to 3×10^-3 Pa) and start heating. (Due to different materials, the process is different) heating is added to the sintering temperature according to the process curve , inflate and cool to the furnace temperature, open the furnace door to take out the workpiece, and complete the entire sintering process.

Vacuum sintering has the following characteristics:

Vacuum sintered products have good compactness, high hardness and stable performance.

The configuration performance of the vacuum system is superior, with large pumping volume and fast pumping speed, which can solve the problem of large outgassing of raw materials.

It can meet the requirements of different process curves, with a high degree of automation and a complete detection system, which can avoid adverse effects caused by some human factors. The vacuum sintering process is flexible, and products of different shapes can be sintered according to different contracts.

3.Development trend of vacuum sintering

The vacuum sintering process is a relatively advanced manufacturing process technology at present, and it is more and more used in the vacuum sintering process of various industries. For example, in the manufacturing processes of semiconductors, ceramics, superhard materials and other fields, vacuum sintering technology and equipment will be used more and more widely.

With the continuous improvement and upgrading of vacuum sintering equipment, its degree of automation and production efficiency will also continue to increase. At the same time, the vacuum sintering process will pay more attention to environmental protection and energy conservation, such as the use of renewable energy, and the reduction of industrial wastewater and exhaust emissions. These measures will further promote the development and application of vacuum sintering technology.

4.Application prospect of vacuum sintering

With the continuous improvement of the degree of industrialization and the continuous advancement of technology, vacuum sintering technology will be applied in more fields. For example, in new materials, new energy, aerospace, automobile and other fields, vacuum sintering technology has broad application prospects. At the same time, as people pay more attention to environmental protection and energy conservation, vacuum sintering technology will gradually replace traditional heat treatment and manufacturing processes and become a more environmentally friendly, efficient and energy-saving manufacturing process.

To sum up, vacuum sintering technology has many features and advantages, and is suitable for manufacturing high-quality, high-performance materials and products. With the continuous advancement of technology and the expansion of application scope, vacuum sintering technology will be widely used and developed in more fields. In the future, vacuum sintering technology will continue to be upgraded and improved to become a more environmentally friendly, efficient and energy-saving manufacturing process, providing more reliable and advanced material preparation and heat treatment technologies for the development and progress of various industries.
