Generally speaking, powder metallurgy oil bearing is mainly made of raw material powder through pressing, sintering, shaping, oil immersion and other processes.

As we all know, the production of mechanical structural parts by powder metallurgy has the advantages of less and no cutting

The periodic law of elements in modern chemistry was initiated by Dmitri Mendeleev, a Russian scientist in 1869. He arranged 63 known elements according to atomic weight and in the form of a table, and put elements with similar chemical properties on the same line, which is the prototype of the periodic table of elements.

Ultrafine zirconium powder was prepared by high purity sponge zirconium, high purity hydrogen deep hydrogenation and gradient dehydrogenation.

Due to the complex structure of gas turbine, the temperature and stress of each part are quite different, so the requirements and selection of materials are different.

Nickel base single crystal superalloy has high temperature bearing capacity and good comprehensive properties. It is considered to be the most promising material for advanced aviation turbine engine blades.
