FIELD: powder metallurgy, namely manufacture of sintered metallic articles with compacted surface.
SUBSTANCE: method comprises steps of high-speed pressing of iron powder or iron base powder till density exceeding 7.2 g/cm3; sintering articles and compacting their surface. Due to high density of non-sintered pressed piece method allows enhance mechanical properties of article.
EFFECT: improved mechanical properties of articles, increased depth of compacted layer, minimum change of blank size at sintering it.
