What is powder metallurgy? Powder metallurgical refers to the process of preparation of metal powder or metal powder (or mixture of metal powder and non -metallic powder) as the raw material, forming and sintering to make metal materials, composite materials and various product technologies. Powder metallurgy has unique chemical composition and mechanical and physical properties, and these properties cannot be obtained through traditional casting methods. Powder metallurgical technology can directly produce porous, semi -dense or full -dense materials, such as oil -containing bearings, gears, cams, guides, tools, etc. This is a rare cutting process.
Powder metallurgy technology can easily achieve a variety of composite materials, and give full play to the respective characteristics of each component material. It is a process technology for low -cost production of high -performance metal matrix and ceramic composite materials. It can greatly reduce the analysis of alloy composition and eliminate the large and uneven tissue of the castings. Preparation of high -performance rare earth permanent magnet materials, rare earth hydrogen storage materials, rare earth luminous materials, rare earth catalysts, high temperature superconducting materials, new metal materials (such as aluminum lithium alloy, heat aluminum alloy, super alloy, powder corrosion -resistant stainless steel, powder high -speed powder Steel, intermediary metal compounds, high temperature structure materials, etc.) plays an important role.
Powder metallurgical method can ensure the correctness and uniformity of the material composition ratio. Therefore, most difficult melting metals and their compounds can only be manufactured by powder metallurgical methods, such as our commonly used processing tools. Hardware grinding tools, etc. It is very suitable for products with the same shape, a large number of products, especially the products with high gears and other processing costs. If the powder metallurgical method is used, production costs can be greatly reduced.
Powder metallurgical products far exceeded the scope of materials and metallurgy, and are usually interdisciplinary (materials and metallurgy, machinery and machinery) technology. In particular, the modern metal powder 3D printing of mechanical engineering, CAD, reverse engineering technology, layered manufacturing technology, CNC technology, material science and laser technology combines the combination of material science and laser technology, making powder metallurgical product technology a modern integration across more disciplines.
