Rust prevention of powder metallurgy parts

Fe-based powder metallurgy is a high-efficiency metal forming process that is material saving, energy saving, non-polluting and suitable for mass production. Because iron-based powder metallurgy parts are made from metal powder through pressing, sintering, machining, heat treatment and other processes, there must be certain pores in the powder metallurgy products, generally containing 10% – 30% of the pores. Compared…

Density of Iron-based powder metallurgy

As we all know, the higher the density of iron-based powder metallurgy, the better the strength, but not all products are suitable for high density. The density of iron-based powder metallurgy is generally 5.8g/cm3-7.3g/cm3, which is determined by the use and structure of the product. In most industries, the density of iron-based powder metallurgy gears is 6.8g/cm3. If necessary,…

Application range of powder metallurgy gears

Powder metallurgy gears are powder metallurgy parts commonly used in various automobile engines. Through a single forming and finishing process, no other post-processing processes are required, and the dimensional accuracy requirements, especially the tooth profile accuracy, can be fully achieved. Therefore, compared with the traditional mechanical processing method, the material input and manufacturing are greatly reduced. It is a…

The influence of sintering temperature on powder metallurgy gear

One of the goals of general sintering is to make the size of the part consistent with the size of the forming cavity. However, the dimensional changes of powder metallurgy products are mainly affected by the characteristics of the raw material powder, forming conditions, sintering temperature and sintering time and other process parameters. These parameters also affect the dimensional…

How to improve the strength and wear resistance of powder metallurgy gears

In order to improve the strength and wear resistance of powder metallurgy gears, we usually need to add post-processing engineering after the powder metallurgy gears are sintered to improve their performance. For example, in the post-treatment of powder metallurgy gears, engineers of powder metallurgy gear manufacturers generally use surface water vapor treatment and carburizing treatment to increase the wear…
