Now
metal powder metallurgy products technology development speed is very fast, in which the metal powder metallurgy technology in the development process there are three important marks:
The first signs are metal powder metallurgy produced refractory metal casting technology to overcome the difficulties in the process of.
Second marks are metal powder metallurgy technology in 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.
The third symbol is the development of metal powder metallurgy technology in the new material and new technology. 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; have been able to make high strength parts using powder metallurgy forging and the hot isostatic pressing.
