Description
(5) СПОСОБ ПОЛУЧЕНИЯ БИМЕТАЛЛИЧЕСКИХ ЗАГОТОВОК(5) METHOD FOR OBTAINING BIMETALLIC BLANKS
1one
Изобретение относитс к порошковой металлургии, в частности к способам получени биметаллических заготовок .The invention relates to powder metallurgy, in particular to methods for producing bimetallic billets.
Известен способ изготовлени биметаллических изделий, включающий напрессовывание порошкового слой на сердечник из компактного материала гор чим изостатическим прессованием и последующую осадку при 10501150 С со степенью деформации 7085 tn.A known method of manufacturing bimetallic products includes pressing a powder layer onto a core of compact material by means of hot isostatic pressing and subsequent sedimentation at 10501150 С with a degree of deformation of 7085 tn.
. Недостаток данного способа заключаетс в склонности получаемых изделий к расслоению и трещинообразованию вследствие внутренних напр жений , возникающих между порошковым слоем и заготовкой за счет различи в теплофизических свойствах.. The disadvantage of this method lies in the propensity of the obtained products for delamination and cracking due to internal stresses arising between the powder layer and the workpiece due to the difference in thermal physical properties.
Наиболее близким по технической сущности и достигаемому результату к изобретению вл етс способ получени биметаллических изделий, включающий установку в iкапсулу сердечника из низколегированнбй стали, загрузку порошка быстрорежущей стали и последующее гор чее прессование 2.The closest in technical essence and the achieved result to the invention is the method of obtaining bimetallic products, including the installation of low-alloyed steel core into the i-capsule, loading of high-speed steel powder and subsequent hot pressing 2.
Однако сердцевина заготовки, формируема из порошковой стали, плохо пропрессовываетс , поэтому заготовки, полученные известным способом имеют нестабильную плотность. Кроме того, However, the core of the billet formed from powder steel is poorly pressed, therefore billets made in a known manner have an unstable density. Besides,
10 при изготовлении крупногабаритных заготовок дл формировани сердцевины требуетс большой расход дорогосто щих порошков, что повышает сто- , имость заготовок.10, in the manufacture of large-sized blanks, a large consumption of expensive powders is required to form the core, which increases the cost of the blanks.

Целью изобретени вл етс повышение качества заготовок.The aim of the invention is to improve the quality of the blanks.
