Summary
-
1.
It has been found possible to use nonprereduced iron and copper powders (PZh-3 and PM-2 powders) in the as-delivered state for serial production of parts made from frictional ceramic mixtures with an iron base.
-
2.
The use of these powders simplifies the technological process, reduces the amount of dust in the shop atmosphere, decreases the labor consumption by 10–15%, and ensures the production of high-grade parts from friction sintered mixtures.
