Vacuum drying is an important part of drying equipment. Although vacuum drying has the disadvantage of high cost, due to its excellent work efficiency, vacuum drying equipment has advanced drying methods, a wide range of applications and an open market prospect. In addition, its green features are also reasons favored by the market. China's drying equipment is mainly distributed in pharmaceutical machinery, mining and metallurgy, chemical machinery, food machinery and other fields. At present, the industry has gradually entered a mature stage, and it can better meet the actual needs of users in various fields. There are many professional drying equipment manufacturers, and their products are both generic and unique. As a green drying equipment, the vacuum dryer has a broad market prospect. Domestic enterprises have accelerated their research on vacuum drying technology. Some enterprises have also made breakthrough progress, reduced energy consumption to a certain extent, reduced pollution, brought more benefits and value to the society, and also obtained for themselves. A larger proportion of dryer market share. However, at this stage, China's vacuum drying equipment manufacturers generally have a low level of innovation capability. Enterprises that can introduce new technologies and new products with independent intellectual property rights are poor, resulting in slow development of drying technology. Knowledge achievements have not been effectively translated into actual productivity. At present, the R&D and innovation of technologies in the field of drying equipment mainly rely on universities and research institutes. Due to the disconnection of companies, it is difficult to effectively turn knowledge achievements into productivity. Therefore, for the domestic vacuum drying equipment manufacturing enterprises, not only fundamental transformation from the drying process, but also a comprehensive, multi-level energy-saving technological transformation, vigorously develop the drying technology using renewable energy and industrial waste heat. It is necessary to thoroughly study the relevant knowledge of the new version of GMP and further promote the development of the equipment toward energy saving, high efficiency, and environmental protection. Through the agglomeration of industries, a large industrial cluster is formed, the industrial chain is lengthened, and a production pattern with interlocking advantages and complementary advantages is formed to enhance the overall competitiveness of the industry. Although there is still a certain gap between the domestic production of drying equipment and developed countries, the advantages of domestically produced equipment are being gradually established, and the domestic market has basically become dominant. Vacuum drying equipment will become the mainstream of market demand. The domestic industry must significantly improve the technical level, improve the drying efficiency, reduce energy consumption, and contribute its own power to achieve green production. Cobalt-based alloy powders are commonly used in plasma transfer arc welding (PTAW) due to their excellent high-temperature properties and resistance to wear and corrosion. These alloys are typically composed of cobalt as the base metal, with various alloying elements such as chromium, tungsten, nickel, and carbon added to enhance specific properties.

The use of cobalt-based alloy powders in PTAW offers several advantages, including:
1. High-temperature strength: Cobalt-based alloys exhibit excellent strength and resistance to deformation at elevated temperatures, making them suitable for welding applications that involve high heat.
2. Wear resistance: These alloys have a high hardness and resistance to wear, making them ideal for welding applications where the welded parts are subjected to abrasive or erosive conditions.
3. Corrosion resistance: Cobalt-based alloys offer good resistance to corrosion, making them suitable for welding applications in aggressive environments, such as those involving chemicals or saltwater.
4. Thermal conductivity: Cobalt-based alloys have good thermal conductivity, allowing for efficient heat transfer during welding and reducing the risk of heat-affected zone (HAZ) defects.
5. Compatibility with other materials: Cobalt-based alloys can be easily welded to a wide range of base metals, including stainless steels, nickel alloys, and other cobalt-based alloys, providing versatility in welding applications.
To use cobalt-based alloy powders for PTAW, the powder is typically fed into the plasma arc using a powder feeder. The powder is then melted by the high-temperature plasma arc and deposited onto the workpiece, forming a weld bead. The specific welding parameters, such as arc current, travel speed, and powder feed rate, will depend on the specific alloy and application requirements.
It is important to note that the selection of the cobalt-based alloy powder should be based on the specific welding application and the desired properties of the final weld. Different cobalt-based a
