Powder metallurgy is the process of making metal powder or using metal powder (or a mixture of metal powder and non-metal powder) as raw material, forming and sintering, and making metal materials, composite materials and various types of products. Powder metallurgy is similar to ceramic production in that both of them belong to powder sintering technology. Therefore, a series of new powder metallurgy technologies can also be used in the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solve the problem of new materials and plays an important role in the development of new materials.
Powder metallurgy includes the making of powder and articles. Among them, the powder is mainly metallurgical process, and literally. Powder metallurgy products, on the other hand, often go far beyond materials and metallurgy and are often technologies that span multiple disciplines (materials and metallurgy, machinery and mechanics, etc.). In particular, modern metal powder 3D printing, which integrates mechanical engineering, CAD, reverse engineering, layered manufacturing, numerical control, material science and laser technology, makes powder metallurgy products technology become a modern comprehensive technology across more disciplines.
Powder metallurgy is an industrial technology for making metal powder or using metal powder (or a mixture of metal powder and nonmetal powder) as raw material, through forming and sintering, to make metal materials, composite materials and various types of products. Powder metallurgy technology has been widely used in the fi复制elds of transportation, machinery, electronics, aerospace, weapons, biology, new energy, information and nuclear industry, and has become one of the most dynamic branches of new material science. Powder metallurgy technology has a series of advantages such as significant energy saving, material saving, excellent performance, high precision and good stability, etc. It is very suitable for mass production. In addition, some materials and complex parts that cannot be made by traditional casting and machining methods can also be made by powder metallurgy technology, which has attracted much attention from the industry.
The broad definition of powder metallurgy products industry includes iron tools, cemented carbide, magnetic materials and powder metallurgy products. The narrow sense of powder metallurgy products industry only refers to powder metallurgy products, including powder metallurgy parts (the majority), oil bearing and metal injection molding products.
Powder metallurgy has unique chemical composition and mechanical and physical properties that cannot be obtained by traditional casting methods. Powder metallurgy technology can be directly made into porous, semi-dense or fully dense materials and products, such as oil bearing, gear, CAM, guide rod, tool, etc., is a less cutting process.
(1) powder metallurgy technology can minimize the bias of alloy components and eliminate the thick and uneven casting structure. It plays an important role in the preparation of high-performance rare earth permanent magnetic materials, rare earth hydrogen storage materials, rare earth luminescent materials, rare earth catalysts, high-temperature superconducting materials, new metal materials (such as al-li alloy, heat-resistant Al alloy, superalloy, powder corrosion-resistant stainless steel, powder high-speed steel, intermetallic compound high-temperature structure materials, etc.).
(2) a series of high-performance non-equilibrium materials such as amorphous, microcrystalline, quasi-crystalline, nanocrystalline and supersaturated solid solution can be prepared. These materials have excellent electrical, magnetic, optical and mechanical properties.
(3) it can easily realize multiple types of composites and give full play to the characteristics of each component material, which is a process technology for low-cost production of high-performance metal matrix and ceramic composites.
(4) it can produce materials and products with special structures and properties that cannot be produced by ordinary smelting methods, such as new porous biomaterials, porous separation membrane materials, high-performance structural ceramic abrators and functional ceramic materials.
(5) near-net formation and automated mass production can be realized, thus effectively reducing the resource and energy consumption of production.
(6) it can make full use of ore, tailings, steelmaking sludge, rolled iron and steel scales, and recycle waste metal as raw materials, which is a new technology that can effectively conduct material regeneration and comprehensive utilization.
Many of our common machining tools and hardware tools are made by powder metallurgy technology.
The wear resistance and antifriction qualities of the oil impregnated sintered bronze make for an excellent guide bushing.
Bearings are a natural product for Oil Impregnated Bushings because of its controlled porosity and the resulting self-contained lubrication. The shaping of a sintered bearing is essentially defined by the tool design and its manufacture. The appropriate layout of the components geometry and the selection of suitable material according to the Oil Impregnated Bushings process has a strong influence on tool life and consequently on the price of the part. It is therefore worthwhile to consider some of the guidelines of design related to the Oil Impregnated Bushings .

As a general rule, walls should not be thinner than 0.060 inch (1.52 mm) and the ratio of the length to wall should be less than 8:1 for tool strength and to ensure that the powder properly fills all sections of the die for proper part density. Avoid designing long, thin walls; they require tooling that is fragile and the parts themselves have a tendency toward density variation. Where the ratio of length-to-wall thickness is as high as 8:1 or more, special precautions must be taken to achieve uniform fill, and variations in density are unavoidable. The lower length to diameter and or length to wall thickness ratios, the easier it becomes to maintain uniform density throughout the part.
The edges of a part must be designed with bevels instead of radii to avoid burrs. At 30-45 degrees. the chamfer with a surface from 0.005 inches (0.13 mm) to 0.015 inches 0.38 mm will eliminate the soft edges, which are undesirable
The Oil Impregnated Bushings is an economical, environmentally clean, high production method for making parts exactly to or close to final dimensions. With little or no machining operations required. Due to their porosity, they may be impregnated with oil or plastic.
Proper development of components for production using the P / M process can minimize or facilitate the need for recycling. With the help of powder metallurgy, we can maintain tight dimensional tolerances and achieve “clean” molding. Reducing technological processes and scrap losses is the biggest benefit of saving powdered metal parts. The P / M process eliminates or minimizes scrap loss, typically using more than 97% of the feedstock in the finished part.
The powdered metal process is suitable for economical, high-volume production. However, National Bronze Mfg. It prides itself on being particularly flexible in terms of volume.
Difference between oil-bearing copper sleeve and self-lubricating copper sleeve in powder metallurgy
Among the types of plain bearings, there are self-lubricating bearings lubricated by the inherent lubricant of the matrix and steel back bearings with anti-wear layer on the working face. Here we mainly explain the oil-bearing copper sleeve and self-lubricating copper sleeve with the matrix lubricant, and then make a detailed analysis of the products with reduced wear layer in the later stage.
Here is the definition of powder metallurgy oil-bearing copper sheath: powder metallurgy is a technology for making metal powder, and taking metal powder (and sometimes adding a small amount of non-metallic powder) as raw material, through mixing, forming and sintering, to make materials or products. Powder metallurgy oil bearing refers to the bearing products processed in this way after the bearing is vacuum impregnated with lubricating oil. Because the matrix of this product is made of powder, there will be fine holes in the matrix, and the oil content can reach a certain proportion after impregnated with lubricating oil. From the beginning in our country will be a name to this bearing oil bearing, oil bearing is not to say that this kind of bearings have oily so when use don't need to add lubricating oil, it is showed that the bearing itself has oil amount of lubricating oil, often don't need to add lubricating oil or when using only a small amount of added lubricant.
Working principle: when the shaft is at rest, all the bearings are stored in the pores, and the load is supported by the direct contact between the oil-bearing bearing and the shaft. However, due to capillarity, when the shaft is in operation, the lubricating oil contained in the fine pores of the bearing material seeps out on the inner diameter surface of the bearing, forming a boundary lubrication of a certain state at the contact point between the shaft and the surface of the bearing. P/m oil-bearing copper sleeve is generally installed at a high speed, inconvenient for refueling and maintenance, with a certain working condition of low temperature and load. However, before processing this kind of product, it is generally necessary to process the mold of the related product first. Therefore, when selecting the product type, if the product size is small and the quantity is particularly large, this process can be considered.
Application conditions: widely used in household electrical machinery, textile machinery, chemical machinery, automobile industry and other fields.
