About powder metallurgy
Powder metallurgy is a modern technological process of production of metal parts and components by using metal powders. This manufacturing method allows you to obtain parts with high accuracy of shape and size, high strength and specific properties that meet the requirements of various industries.
The main process of powder metallurgy includes the following steps (stages):
The first stage is the preparation of the mixture. Metal powders can be obtained by grinding metal or atomization (spraying) of molten metal. This makes it possible to obtain finely dispersed powder with different fractions. Powders can be mixed with additional components such as lubricants, additives or lubricants. This helps to improve the workability of the powder and the properties of the finished part.
Next, the compacting process is carried out, where the mixed powder is placed in a special mold and subjected to high pressure to create a green part. In this process, the powder is compacted, but not completely sintered.
The next stage is sintering. The green part is subjected to high temperature in a special furnace. Under the influence of pressure and temperature, the powder is completely sintered, welded together, and forms a finished metal part. In this process, diffusion occurs between powder particles, which leads to the formation of bonds and interactions between metal atoms.
Processing and finishing. Finished sintered parts can be subjected to processing, such as milling, drilling, grinding or polishing, to achieve precise geometric parameters and surface quality.
The advantages of powder metallurgy include: high accuracy of the shape and size of the part; the possibility of manufacturing complex geometric shapes and structures; high strength and hardness of finished parts; minimal loss of material, as the powder can be used effectively; the ability to control the composition and properties of the part by using different types of powders and additional components.
Powder metallurgy is widely used in the production of the automotive industry, mechanical engineering, electronics, medical production and many other industries where the quality, precision and strength of manufactured parts are important.
What are the advantages of manufacturing parts using powder metallurgy?
COMPLEX FIGURES
Sintering allows complex shapes to be obtained directly from the sealing tool without any machining, such as teeth, slots, profiles, face geometry, etc.
HIGH ACCURACY OF DIMENSIONS
Achievable tolerances in the perpendicular direction of the seal are typically IT 8-9 as sintered, can be increased to IT 5-7 after sizing. IT 10-13 is reached in length depending on the geometry of the component; additional processing operations can improve this accuracy.
RELIABILITY AND REPEATABILITY IN LARGE SERIES PRODUCTION
The stability of the tool, the technical complexity of the production devices and the SPC control system ensure high reliability and repeatability of mass-produced sintered components.
SELF-LUBRICATION
The interconnected porosity of the material can be filled with oils, resulting in a self-lubricating bearing: the oil provides constant lubrication between the bearing and the shaft, and the system does not require additional external lubrication.
UNIQUE AND ISOTROPIC MATERIALS
Sintered materials have a homogeneous microstructure in three spatial directions, so the properties are isotropic. In addition, the solid-state diffusion mechanism used to create the microstructure allows the creation of compositions and materials that cannot be obtained by melting, such as composite materials made of insoluble or immiscible phases or microinsulating materials.
GREEN TECHNOLOGIES
The production process of the sintered components is certified as environmentally friendly because the material waste is very low, the product is recyclable and the energy efficiency is good because the material is not melted.
EXCELLENT SURFACE
The surface of sintered components is characterized by the presence of flat areas with very low roughness interspersed with dips corresponding to porosity. This surface condition is better than that of machined materials, which have alternating peaks and troughs. The presence of smaller peaks allows to reduce the time of running-in of the components.
EXTINGUISHING VIBRATION
The internal microporosity of sintered parts creates a damping effect on the propagation of vibration.
WEIGHT REDUCTION
Thanks to internal microporosity, sintered parts are typically 5-25% lighter than the same forged components.
