Description
ОГНЕУПОРНЫЙ МАТЕРИАЛREFRACTORY MATERIAL
Изобретение относитс к порошковой металлургии .The invention relates to powder metallurgy.
Известны высокотемпературные материалы на основе нитрида алюмини , обладающие удельным электросопротивлением более ом-см, высокой химической устойчивостью к агрессивиым средам и диссоциирующий без плавлени ири температуре выше 2200°С.High-temperature materials based on aluminum nitride are known, having a specific electrical resistance of more than ohm-cm, high chemical resistance to aggressive media and dissociating without melting at temperatures above 2200 ° C.
Целью изобретени вл етс повышенне термической стойкости и механической прочности огнеупорного материала.The aim of the invention is to increase the thermal resistance and mechanical strength of the refractory material.
Это достигаетс тем, что в огнеупорный материал ввод т наполнитель в виде волокон тугоплавкого металла, например, вольфрама, молибдена в количестве 1-50 вес. % длиной 2-3 льи и диаметром соответственно 0,020 мм и 0,045 мм.This is achieved by introducing into the refractory material a filler in the form of fibers of a refractory metal, for example, tungsten, molybdenum in an amount of 1-50 wt. % length 2-3 Lions and a diameter of 0.020 mm and 0.045 mm, respectively.
Технологи изготовлени изделий из огнеупорного материала на основе нитрида алюмини заключаетс в прессовании заготовок из смеси 50-99 вес. % порошка нитрида алюмини и 1-50 вес. % волокон вольфрама (молибдена) н их последующем спекании при температуре 1700°С, если используют волокна вольфрама. При использовании волокои молибдена их спекают при 1600°С в азоте в засыпке из нитрида бора. Дл изготовЕИ5The technology for manufacturing products from an aluminum nitride-based refractory material consists in pressing blanks from a mixture of 50-99 wt. % of aluminum nitride powder and 1-50 wt. % of tungsten (molybdenum) fibers and their subsequent sintering at a temperature of 1700 ° C, if tungsten fibers are used. When used, molybdenum fibers are sintered at 1600 ° С in nitrogen in boron nitride bedding. For manufacturing5
лени изделий примен ют также метод взрывного прессовани прп динамических давлени х 20-40 кбар.Products also use the method of explosive pressing of dynamic pressures of 20–40 kbar.
Свойства материала нредставлеиы в таблице .Material properties are shown in the table.
Полученный материал может быть использован в качестве высокотемпературного огнеупорного и ко} струкциоиного материала, способного выдерживать резкие теплосмены без разрушени н работать в агрессивных средах . 34The resulting material can be used as a high-temperature refractory and co-structural material that can withstand abrupt heat exchanges without destruction and work in corrosive environments. 34
