The pressure and heating are carried out in the same process, and the compact sinter can be obtained after a short time of sintering, which greatly reduces the cost.
Under high temperature and high pressure, the advantage of using artificial graphite material have a distinct advantage compared with other materials. Because the coefficient of linear expansion of artificial graphite material is small, the shape and size stability of products produced by it are very high.
Powder metallurgy (PM) is a kind of technology which uses metal powder as raw material, through forming and sintering, to manufacture metal materials, composite materials and various types of products.
