Powder metallurgy is the industry that manufactures metal powders and uses metal powders (including a small amount of non-metal powders) as raw materials, and uses the forming-sintering method to manufacture materials and products. With the development of modern powder metallurgy manufacturing technology, powder metallurgy products can replace conventional metal casting, forging, cutting, and mechanical parts with complex structures that are difficult to cut, and their supporting applications continue to expand. From general machinery manufacturing to precision instruments, from hardware tools to large-scale machinery, from electronics industry to motor manufacturing, from civil industry to military industry, from general technology to cutting-edge high technology, powder metallurgy can be seen. In the field of civil industry, powder metallurgy products have become indispensable basic components for industries such as automobiles, motorcycles, home appliances, power tools, agricultural machinery, and office appliances. The huge potential of the market is also driving technological progress. As powder metallurgy products become more and more widely used, the requirements for the size, shape and performance of metal powder particles are getting higher and higher, and the performance and size and shape of metal powder depend to a large extent on the production method and preparation of the powder Technology, so the powder preparation technology is also constantly developing and innovating.
Atomization, an advanced powder technology, is widely applied in metal powder production. This is a method of directly crushing liquid metal or alloy to obtain powder is called atomization method, which is the most widely used metal powder preparation method second only to reduction method in production scale. Atomized powder has the advantages of high sphericity, controllable powder particle size, low oxygen content, low production cost and adaptability to the production of various metal powders. It has become the main development direction of high-performance and special alloy powder preparation technology, but the production efficiency is low. The yield of ultra-fine powder is not high, and the relatively large energy consumption limits the application of the atomization method.
