METHOD OF MANUFACTURE OF POWDER ALL-MOULDED MULTILAYER ARTICLES

摘要

FIELD: powder metallurgy. SUBSTANCE: method of manufacture of all-moulded bimetallic and multilayer powder articles consists in the fact that moulding of vertically arranged layers is accomplished by setting-up of electromagnetic field in the pressing cavity after filling of powders of the first layer, charging of powder of the next composition for moulding of the second layer. After that the electromagnetic field is cut off and joint moulding of powders and ejecting of compact of articles is carried out. EFFECT: enhanced quality of manufacture of multilayer articles with vertically arranged layers, considerably reduced expenditures connected with materials and their manufacture. 2 dwg
