SINTERED METALLIC COMPOSITION OF MATTER, CONTAINING SECONDARY AMIDES IN CAPCITY OF LUBRICANT AND/OR BINDING AGENT Russian patent published in 2009 - IPC B22F1/00 C22C33/02 B22F3/12 

FIELD: metallurgy.

SUBSTANCE: invention relates to powder metallurgy. Particularly it relates to sintered metallic composition of matter on the basis of iron. Composition of matter contains powder on the basis of iron and lubricant and/or binding agent, containing at least one secondary amide with common formula R₁-NH-CO-R₂, where R₁ and R₂ - are equal or different, linear or branch, saturated or unsaturated aliphatic hydrocarbon groups. Admixture containing at east one secondary amide can be used in the capacity of lubricating and/or binding component for powders on the basis of iron, and also in the capacity of lubricant for die wall.

EFFECT: composition of matters usage provides effort decreasing for pressed details ejection and to decrease surface defect after sintering.
