How to prevent rust of powder metallurgy gears

anti-rust oil protect the Powder metallurgy gear from rust After the production of powder metallurgy gears is completed, in order to prevent the gears from rusting during storage and transportation, a certain amount of powder metallurgy anti-rust oil is usually sprayed on the surface before packing the gears to prevent the gears from rusting. After being sprayed with powder…

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…

Powdered Metal Gears

Powdered metal gears are made through the process of powder metallurgy. There have been many advances to this process over the years, which have in turn caused an increase in the popularity of powdered metal as a gear material. Powdered metal gears are used in many industries, but are used most in the automotive sector. Typical automotive applications include…

Powder metallurgy bearing also called oil-bearing bearings, what’s the advantages?

What’s is powder metallurgy bearing? Powder metallurgy bearings are made of metal powder and other anti-friction material powders pressed, sintered, shaped and oil-impregnated. They have a porous structure. After being soaked in hot oil, the pores are filled with lubricating oil. The suction effect and frictional heating cause the metal and oil to expand by heating, squeezing the oil…

Powder Metallurgy Sintering process

Sintering is a heat treatment applied to a powder compact in order to impart strength and integrity. The temperature used for sintering is below the melting point of the major constituent of the Powder Metallurgy material. After compaction, neighbouring powder particles are held together by cold welds, which give the compact sufficient “green strength” to be handled. At sintering…
