Analysis of powder metallurgy technology and its application

The application of powder metallurgy technology in ancient times, the first method of making iron is essentially used in powder metallurgy. And the development of modern powder metallurgy technology, there are three important signs:

1, to overcome the difficulties produced in the process of refractory metal casting, in 1923 powdermetallurgy cemented carbide was hailed as a revolution in machining.

2, thirty years, the successful preparation of porous oil bearing; and then the development of powder metallurgy iron based machinery parts, and give full play to the advantages of powder metallurgy less cutting and cutting.

3, in the 1940s, metal ceramic, dispersion strengthened materials such as, from the late 1960s to early 1970s, high-speed steel powder, Powder Superalloy have appeared, and the powder metallurgy forging and hot pressing technology gradually large-scale manufacturing parts with complicated shape and high strength.
