Characteristics and functions of metal powder metallurgy technology: Powder metallurgy technology can greatly reduce the segregation of alloy components and eliminate coarse and uneven casting structures. It plays an important role in the preparation of rare earth permanent magnet materials, rare earth hydrogen storage materials, rare earth luminescent materials, rare earth catalysts, high-temperature superconducting materials, and new metal materials (such as Al-Li alloys, heat-resistant Al alloys, superalloys, powder corrosion-resistant stainless steel, powder high-speed steel, intermetallic compound high-temperature structural materials, etc.).

During the sintering process, the powder particles of the powder metallurgy fishing sinker undergo a series of physical and chemical processes such as diffusion, recrystallization, welding, combination, and dissolution to form It is a metallurgical product with a certain porosity.

Then comes the post-processing. In general, powder metallurgy tungsten alloy tool accessories, sintered parts can be directly used in Shandong powder metallurgy. However, for some parts with high dimensional precision, high hardness and wear resistance, sintering post-processing is required. Post-processing includes precision pressing, rolling, extrusion, quenching, surface quenching, oil immersion, and infiltration.

The molten salt aging method is used to precipitate metal powder from molten salt; the metal bath method is used to precipitate metal compound powder from auxiliary metal bath.

The aqueous solution electrolysis method is used to electrolyze metal salt solution to produce metal and alloy powder; the molten salt electrolysis method is used to electrolyze metal and metal compound powder from molten salt.

The gaseous state makes metal or metal compound into powder Methods:

The steam condensation method is used to prepare metal powder from metal vapor condensation;

The powder metallurgy products industry includes iron and stone tools, cemented carbide, magnetic materials and powder metallurgy products. The narrow sense of the powder metallurgy products industry refers only to powder metallurgy products, including powder metallurgy parts (accounting for the vast majority), oil-containing bearings and metal injection molding products.

The pulse current passes through the powder particles during SPS sintering as shown in Figure 2. During the SPS sintering process, the discharge plasma generated instantly when the DC pulse current is passed through the electrode causes each particle inside the sintered body to evenly generate Joule heat and activate the particle surface. Powder metallurgy tool accessories. Similar to the self-heating reaction synthesis method (SHS) and microwave sintering, SPS is an effective method to utilize the self-heating effect inside the powder. Sintering is carried out by SPS. The SPS sintering process can be regarded as the result of the combined effects of particle discharge, conductive heating and pressure.

When sintering ferroelectric ceramic PbTiO3 by SPS, it is sintered at 900-1000℃ for 1-3min. After sintering, the average particle size is <1μm and the relative density exceeds 98%. Since there are few pores in the ceramic [31], the dielectric constant basically does not change with frequency between 101 and 106HZ.

When preparing ferroelectric Bi4Ti3O12 ceramics by SPS, the ceramics are rapidly densified while the grains of the sintered body are elongated and coarsened. It is easy to obtain samples with good grain orientation by SPS. It can be observed that the electrical properties of Bi4Ti3O12 ceramics with preferred grain orientation have strong anisotropy.

The preparation of ferroelectric Li-substituted IIVI semiconductor ZnO ceramics by SPS increases the ferroelectric phase transition temperature Tc to 470K, while the previous cold-pressed sintered ceramics were only 330K.

In the preparation of amorphous alloys, the alloy composition must be selected to ensure that the alloy has an extremely low critical cooling rate for amorphous formation, thereby obtaining extremely high amorphous forming ability. In terms of preparation technology, there are mainly metal casting and water quenching methods, the key of which is rapid cooling and control of non-uniform nucleation. Since the technology for preparing amorphous alloy powder is relatively mature, for many years, the amorphous powder has been used to prepare bulk amorphous alloys by warm extrusion, warm rolling, impact solidification and isostatic sintering at a temperature below its crystallization temperature.

MIM is the abbreviation of Metal Injection Molding, which is a near-net-shape molding technology that injects metal powder into a mold after mixing and kneading with a binder. Zhongwei Precision MIM Project was established in 2003, mainly engaged in the research and development and production of tungsten alloy MIM and titanium alloy MIM. As the project continues to grow and develop, production lines for metals such as stainless steel have been added. At present, the project has MIM and processing platforms and production lines for tungsten alloy, stainless steel, iron-based alloy, copper alloy, soft magnetic material, non-magnetic steel and other materials, and has sintering equipment such as atmosphere-protected push plate furnace and vacuum furnace, with a monthly production capacity of more than 50 million pieces.
