Description
Изобретение относитс к порошковой металлургии и может быть использовано при изготовлении деталей из металлических порошков, преимущественно порошков на основе железа с повышенными пластическими свойствами.The invention relates to powder metallurgy and can be used in the manufacture of parts from metal powders, mainly iron-based powders with enhanced plastic properties.
Целью изобретени вл етс повыше- ние пластичности.The aim of the invention is to improve ductility.
Согласно способу изготовлени деталей , включающему приготовление шихты путем смешивани исходных компонентов, ее прессование и спекание в восстановительной атмосфере при 1100-1200°С, перед приготовлением шихты определ ют массовую долю кислорода и углерода в исходных компонентах, перед смешиванием в шихту ввод туглеродсодержащие вещества в виде смеси графита и стеарата цинка при следующем соотношении компонентов:According to the method of manufacturing parts, which includes preparing the charge by mixing the starting components, pressing and sintering it in a reducing atmosphere at 1100-1200 ° C, before preparing the charge, determine the mass fraction of oxygen and carbon in the starting components, before mixing into the mixture, entering the carbon-containing substances in the form of a mixture of graphite and zinc stearate in the following ratio of components:
Мг КгМк-Мс/К2-Му,Mg KgMk-MS / K2-Mu,
где Му, Мк - массовые доли углерода и кислорода в исходных компонентах;where Mu, Mk are the mass fractions of carbon and oxygen in the initial components;
Мг и Мс - массовые доли графита и стеарата цинка, вводимые в шихту, причем ,2-1,0%;Mg and MS - mass fractions of graphite and zinc stearate, introduced into the mixture, moreover, 2-1.0%;
,6-1,0; K2-12-16., 6-1,0; K2-12-16.
Способ осуществл етс следующим образом .The method is carried out as follows.
Определ ют массовую долю углерода и кислорода в исходном порошке. Составл ют шихты с добавками углеродсодержащих веществ в виде смеси графита и стеарата цинка в пропорции, определ емой указанной формулой. Прессукгршихту в пресс-форме . Спекают заготовки в восстановительной атмосфере при 1100-1200°СThe mass fraction of carbon and oxygen in the starting powder is determined. The mixtures are made with additives of carbon-containing substances in the form of a mixture of graphite and zinc stearate in the proportion defined by the indicated formula. Pressukrashtuyu in the mold. Sinter blanks in a reducing atmosphere at 1100-1200 ° C
