Powder Metallurgy Technology Can Greatly Reduce Alloy Component Segregation!

Powder metallurgy technology can greatly reduce alloy component segregation!
Iron based alloy powder is a process technology for manufacturing metal materials, metal based composite materials, and their products using metal powder (or a mixture of metal powder and non-metallic powder) as raw materials, through forming and sintering. Powder metallurgy process can produce materials that cannot be produced by other processes, and has the characteristics of less cutting or no cutting when manufacturing mechanical parts.
Powder metallurgy technology can greatly reduce alloy component segregation and eliminate coarse and uneven casting structures.
Powder metallurgy sometimes also produces some hazards, such as the materials used sometimes have radioactivity, most powders are flammable and explosive substances that are prone to explosion, and sometimes dust is improperly protected, which can enter the human body and cause harm to the human body. Therefore, people engaged in related industries should pay attention to labor protection.
The main methods for preparing iron powder include reduction, atomization, mechanical pulverization, carbonylation, and electrolysis. The reduction method is commonly used to produce iron powder using iron concentrate and iron scale as raw materials.
The density and consistency of iron powder compacts have an important impact on the sintering density, sintering structure and properties, and product dimensional stability of iron based powder metallurgy materials. Powder flowability is related to many factors, such as powder particle size, shape, roughness, specific surface area, and so on. Generally speaking, increasing the friction coefficient between particles can make it difficult for the powder to flow. Generally, powder with spherical particles has good fluidity, while powder with irregular shape, small size, and rough surface has poor fluidity.
With the continuous development of iron based powder metallurgy parts into the field of manufacturing key automotive components, the market demand for high density and high-performance iron based powder metallurgy parts will become increasingly large, and the performance requirements will inevitably become higher and higher.
The basic and core raw material of the powder metallurgy industry is metal powder, so tall powder metallurgy products often require tall metal powder as the foundation.
