How to deal with the strength and precision of powder metallurgy gear processing?

Nov 28, 2022

Powder metallurgy is a very popular and commonly used processing technology in various fields. Metallurgy has the advantages of easy forming, fast processing, reducing material waste, improving material utilization, less or no cutting, one-time forming, and high precision, which is superior to traditional processing and forming technology. Gear parts have high requirements for accuracy, strength and hardness. So how to deal with the strength and precision of powder metallurgy gear processing? ABCDPrecise Powder Metallurgy Sharing:

1: How to deal with the strength of powder metallurgy?

It can be used as gear material, with low carbon content, to control the carburized layer, and a small amount of fine iron powder can be used to increase the base material. Strength, or adding some active sintering auxiliary materials, can effectively improve the strength of gears.

2: How to deal with the precision of powder metallurgy?

The precision of P/M gears must control the expansion coefficient of materials and the precision of dies. Grade 8-9. If the gear mould imported from abroad is about Grade 7-8, especially the helical gear, it will be a higher grade and higher precision product.

3: How to deal with the hardness of powder metallurgy?

The hardness of powder metallurgy gear is closely related to the density grade of the gear and the subsequent details. Zhongwei precise suggestion: increase the treatment methods such as steam treatment and carburizing treatment on the gear surface after powder metallurgy sintering to improve the hardness of the gear, and also improve the wear resistance in the use process, with a longer service life and more safety.
