Изобретение относитс к области порошковой металлургии, в частности к получению изделий на основе железа путем прессовани и спекани смесей исходных компонентов, в процессе приготовлени которых осуществл ют введение легирующих компонентов, например фосфора, меди, никел , марганца, с целью улучшени физико-механических свойств спеченных изделий.The invention relates to the field of powder metallurgy, in particular to the production of iron-based products by pressing and sintering mixtures of the starting components, during the preparation process of which the introduction of alloying components, such as phosphorus, copper, nickel, manganese, is carried out in order to improve the physical and mechanical properties of sintered products.
Известен способ получени спеченных изделий на основе железа, легированных фосфором , никелем, медью, хромом и другими металлами , который предусматривает приготовление смеси порошков железа с легирующими компонентами, вз тыми в виде лигатуры Fe- Р, Ni-Р, Си-Р, ее прессование и спекание.A known method for producing sintered iron-based products alloyed with phosphorus, nickel, copper, chromium and other metals, which involves the preparation of a mixture of iron powders with alloying components taken as Fe-P, Ni-P, Cu-P, pressing. and sintering.
Недостатком известного способа вл етс необходимость приготовлени лигатуры заданного состава, а также трудность достижени равномерного распределени легирующих компонентов при смешивании порошков.The disadvantage of this method is the need to prepare a master alloy of a given composition, as well as the difficulty of achieving a uniform distribution of the alloying components when mixing the powders.
Целью изобретени вл етс повышение равномерности распределени легирующих компонентов в объеме издели .The aim of the invention is to increase the uniform distribution of the alloying components in the volume of the product.
Дл достижени поставленной цели предлагаетс способ, который отличаетс от известного тем, что легирующие компоненты ввод т в смесь в виде порошков фосфорнокислых солей легирующих металлов.In order to achieve this goal, a method is proposed which differs from the known one in that the alloying components are introduced into the mixture in the form of powders of phosphate salts of the alloying metals.
Пример. Исходную смесь из порошков железа, фосфорнокислого марганца Мп(П2РО4)2 -21120, вз того из расчета содержани фосфора в шихте 0,6%, с добавками карандашного графита (1-1,5%) и стеарата цинка (1%) перемешивают в смесителе в течение 1,5-2 час. Из полученной шихты прессуют издели с остаточной пористостью 17-28%, которые спекают в печах в восстановительной атмосфере при ИЗО-1150°С в течение 1,5-2 час.Example. The initial mixture of powders of iron, manganese phosphate, Mn (P2PO4) 2 -21120, taken from the calculation of the phosphorus content in the mixture of 0.6%, with the addition of pencil graphite (1-1.5%) and zinc stearate (1%) is mixed in mixer for 1.5-2 hours. From the resulting mixture is pressed products with a residual porosity of 17-28%, which is sintered in furnaces in a reducing atmosphere at ISO-1150 ° C for 1.5-2 hours.
После дополнительной механической обработки получают издели , предназначенные дл работы в узлах сухого трени .After additional machining, products are obtained for working in the dry friction units.
Введение легируюших компонентов в виде порошков фосфорнокислых солей легирующих металлов позвол ет достичь более равномерного распределени легирующих компонентов в объеме издели по сравнению с введением их в виде лигатуры Me-Р, что приводит к увеличению прочности изделий в 1,5- 2 раза .The introduction of alloying components in the form of powders of phosphate salts of alloying metals makes it possible to achieve a more uniform distribution of alloying components in the volume of the product as compared with their introduction in the form of a Me-P master alloy, which leads to an increase in the strength of products 1.5-2 times.
Предмет изобретени Subject invention
Способ изготовлени спеченных изделий на основе железа, включающий смещивание порощка железа с легирующими компонентами, прессование и спекание, отличающийс тем, что, с целью повышени равномерности 3 распределени легирующих компонентов объеме издели , последние ввод т в смесь 482247 4 в виде порошков фосфорнокислых солей легирув ющих металлов.A method of manufacturing sintered iron-based products, comprising displacing the iron powder with alloying components, pressing and sintering, characterized in that, in order to increase the uniformity of the 3 distributions of the alloying components to the product volume, the latter are introduced into the mixture 482247 4 in the form of powders of phosphoric acid salts metals.
