The method for preparing the composition of powder metallurgy, and method for preparing articles summarized

摘要

The composition of powder metalurgico), compacted, and methods for preparing a composition of powder metalurgico and to prepare articles summarized are provided methods for preparing components summarized high density which increases the capacity of lubricating compositions of powder me Talu00fargico, reducing the general content of the organic component compressed.Preparation method of high density compacted components with a high density includes the steps of providing a composition of powder metallurgy with coated particles at least partially with a layer of metal phosphate, and summarize the composition of powder metallurgy in kill Iz at a pressure of at least about 5 IST (77 MPa).The composition of powder metallurgy comprises a powdered base metal, alloy, and an optional post internal lubricant particles. The metal phosphate is at least partially the base metal powder, alloy powder is optional, or both.The coating of metal phosphate increases the ability of lubricating powder for metallurgy, without the need of large quantities of organic material, for example, lubricants and binders.
