Description

Компактные издели , например электроды, получают холодным прессованием порошка {Лфесс 2т/см2) с последующим спека)1йем в водороде при 1350°С (точка росы 40°С) в течение 1 ч.Compact products, such as electrodes, are obtained by cold pressing the powder (Less 2t / cm2) followed by spec) first in hydrogen at 1350 ° C (dew point 40 ° C) for 1 hour.

Пример 2. Получение исходного материала дл  электродов состава W + 3,0%Ni + 2,6% СаО.Example 2. Preparation of starting material for electrodes of composition W + 3.0% Ni + 2.6% CaO.

В 550 мл дистиллированпой воды раствор ют 78,5 г азотнокислого кальци  Са(МОз)24Н2О марки ЧДА и 85 г азотнокислого никел  М1(МОз)2-6Н20 марки ЧДА. К раствору добавл ют при перемешивании порошок вольфрамового ангидрида марки ЧДА - 590 г.In 550 ml of distilled water, 78.5 g of calcium nitrate Ca (Moz) 24Н2О of the analytical grade and 85 g of nickel nitrate M1 (Moz) 2-6Н20 of the analytical grade are dissolved. To the solution was added with stirring a powder of tungsten anhydride brand ChDA - 590 g.

В иолученную суспензию при непрерывном перемешивании ввод т раствор углекислого аммони  (NH4)2CO3 марки ЧДА (139,5 г в 1300 мл воды). Осадок отдел ют фильтрованием , сушат при 130-150°С, восстанавливают в водороде ири 850°С (точка росы 40°С). Выход 500 г порошка. Химический состав порошка: никель-3,0%, окись кальии -3,6%, вольфрам - остальное. Компактные издели  и,,готавливают известными методами иорошковой металлургии. Материал отличаетс  равномерным распределением присадок. Плотность компактных изделий составл ет 99,8% от теоретической.With continuous stirring, a solution of ammonium carbonate (NH4) 2CO3, grade of analytical grade (139.5 g in 1300 ml of water) is injected into the suspension. The precipitate is separated by filtration, dried at 130-150 ° C, reduced to hydrogen at 850 ° C (dew point 40 ° C). Output 500 g of powder. The chemical composition of the powder: Nickel-3.0%, calcium oxide -3.6%, tungsten - the rest. Compact products and, are prepared by known methods of powder metallurgy. The material is characterized by a uniform distribution of the additives. The density of compact products is 99.8% of theoretical.

Предложенный способ иозвол ет получить равномерное распределение присадок в материале , вследствие чего обесиечиваетс  более высока  механическа  обрабатываемость материала и улучшаетс  качество электродоз.The proposed method makes it possible to obtain an even distribution of the additives in the material, as a result of which a higher mechanical processability of the material is achieved and the quality of the electrodes is improved.
