Process and material analysis of powder metallurgy

Nov 13, 2022

What are the changes of powder metallurgy process and materials? In recent years, with the gradual development and sophistication of materials, equipment, molds, processes, and automation skills, powder metallurgy has been used more and more widely, and has become a new industrial skill that is highly valued in consumer electronics, cars, and other professions. What are the powder metallurgy processes and data? Let's share it with you. Let's have a look:

Powder metallurgy is a processing method for making metal powder and making metal powder or mixture of metal powder and non-metallic powder into products through forming and sintering processes. It can not only make special materials that are difficult to make by general smelting methods, but also make various fine mechanical parts, saving labor and materials. However, its mold and metal powder are expensive, and should not be used when the batch size is small or the product size is too large. Compared with traditional materials and processes, powder metallurgy materials and processes have the following characteristics:

1. The powder metallurgy process is carried out at a melting point lower than that of the base metal, so it is possible to obtain multi-phase heterogeneous composite materials and products of various metals, metals and ceramics, metals and plastics, etc. with different melting points and densities.

2. Improve the data function. The fine metal or alloy powder prepared by special methods has extremely fast condensation speed and fine and uniform grains, which ensures the uniform arrangement of data, stable functions, and outstanding cold and hot processing functions. Moreover, the powder particles are not restricted by alloy elements and content, which can improve the phase content, and then develop a new data system.

3. By using various forming processes, powder materials can be directly formed into blank or net shaped parts with little or no allowance, and many machining quantities can be reduced. Improve the utilization rate of materials and reduce costs.

There are many kinds of powder metallurgy, mainly including: refractory metals such as tungsten and alloy products;

Tungsten carbide (WC), titanium carbide (TiC), tantalum carbide (TaC) and other hard alloys with Co, Ni, etc. as binders are used to make drill bits, turning tools, milling cutters in cutting tools and wear-resistant tools, as well as molds;

Porous materials such as Cu alloy, stainless steel and Ni are used to make sintered oil bearing, sintered metal filter and textile ring. With the development of powder metallurgy production skills, powder metallurgy and its products will be more widely used.
