Description
Изобретение относитс к области порошковой металлургии, в частности к производству рлеталлокерамических изделий путем деформации спеченных заготовок.The invention relates to the field of powder metallurgy, in particular to the production of metal-ceramic products by deformation of sintered billets.
Известный способ изготовлени металлокерамических изделий и полуфабрикатов предусматривает деформацию спеченной заготовки, обладающей высокой плотностью. Применение известного способа дл деформации высокопористых заготовок вызывает разрушение деформируемых заготовок и снижение качества изделий .A known method of manufacturing cermet products and semi-finished products involves the deformation of a sintered billet of high density. The application of the known method for the deformation of highly porous workpieces causes the destruction of deformable workpieces and a decrease in the quality of products.
С целью придани пластических свойств высокопористым металлокерамическим материалам предлагаетс пропитывать их перед деформацией вешествамп, обладаюшими высокой смачиваюшей способностью.In order to impart plastic properties to highly porous ceramic-metal materials, it is proposed to impregnate them before deformation in high-wetting properties.
Пример. Смесь порошков железа и легированной стали прессуют при комнатной температуре в закрытой лресс-форме. 1-1зделие, полученное после прессовани , спекают в проходной электрической печи в защитной атмосфере диссоциированного аммиака. Температура спекани 1250°С, продолжительность спекани 12 час. После спекани полученное изделие отжигают в течение 10 час при 750°С. Подготовленное таким образом изделие пропитывают парафином путем погружени его в расплав 120-130°С. Пропитаппое изделие подвергают деформации путем закрытого холодного выдавливани .Example. A mixture of powders of iron and alloy steel is pressed at room temperature in a closed latency form. The 1-1 product obtained after pressing is sintered in a continuous electric furnace in the protective atmosphere of dissociated ammonia. The sintering temperature is 1250 ° С, the duration of sintering is 12 hours. After sintering, the resulting product is annealed for 10 hours at 750 ° C. The product prepared in this way is impregnated with paraffin by immersing it in the melt at 120-130 ° C. The impregnated article is deformed by closed cold extrusion.
Использование предложенного способа позвол ет повысить пластичность издели , что в свою очередь создает возможность деформировани издели с высокой исходной пористостью , например с пористостью выше 30%, вUsing the proposed method allows to increase the plasticity of the product, which in turn creates the possibility of deforming the product with a high initial porosity, for example with a porosity higher than 30%, in
то врем как известное техническое решение обеспечивает пластическое деформирование издели с пористостью не выше 20%. Повышение пластичности изделий позвол ет улучшить качество получаемых изделий, снизитьWhile the known technical solution provides plastic deformation of the product with a porosity not higher than 20%. Improving the plasticity of products allows to improve the quality of the products, reduce
примен емые усили деформации и увеличить степень деформации спеченных изделий с высокой пористостью.applied deformation forces and increase the degree of deformation of sintered products with high porosity.
Предмет изобретени Subject invention
