Description
Известны металлокерамические материалы, изготовл емые из горных пород, например, из базальта с добавкой глины, фосфорнокислых и углекислых солей, пластификаторов . Отпрессованные из смеси таких материалов издели подвергают обжигу до спекани .Metal-ceramic materials made from rocks are known, for example, from basalt with the addition of clay, phosphate and carbonate salts, plasticizers. Pressed from the mixture of such materials, the products are fired prior to sintering.
Описываемый металлокерамический материал отличаетс от известных тем, что в его состав ввод т чугун, а обжиг отформованного издели осуществл ют в атмосфере окиси углерода, с целью образовани сцементированных частиц карбидов железа.The described cermet material differs from the known ones in that cast iron is introduced into it, and the molded product is calcined in an atmosphere of carbon monoxide to form cemented particles of iron carbides.
Технологический процесс изготовлени изделий из предлагаемого металлокерамического материала следуюш,ий.The technological process of manufacturing products from the proposed cermet material is the following, i.
Из базальта, туфа, диабаза или другой горной породы и чугунной стружки изготовл ют тонкодисперсные порошки. Затем составл ют смесь, содержащую горную породу и чугун, в соотнощении от 1:0,6 до 1 :1.Fine powders are made from basalt, tuff, diabase or other rock and cast iron shavings. Then a mixture comprising rock and cast iron is made in a ratio from 1: 0.6 to 1: 1.
К этой смеси добавл ют пластификатор в пропорции от 1:0,2 до 1 :0,3; причем пластификатор должен быть предварительно разведен в воде в пропорции от 1:0,5 до 1:1.A plasticizer is added to this mixture in a proportion of 1: 0.2 to 1: 0.3; moreover, the plasticizer must be pre-diluted in water in a ratio of from 1: 0.5 to 1: 1.
Тщательно перемешанную смесь металлокерамической массы с пластификатором подвергают сунлке до получени массы 8-10%-ной влаги, из которой и формуют издели .Thoroughly mixed mixture of metal-ceramic mass with a plasticizer is subjected to a sunlka to obtain a mass of 8-10% moisture, from which the product is molded.
Отформованные издели сущат до полного удалени влаги, затем обжигают при 1140-1160° в атмосфере окиси углерода, после чего медленно охлаждают.The molded articles are present until moisture is completely removed, then they are calcined at 1140–1160 ° in an atmosphere of carbon monoxide, and then slowly cooled.
Предлагаемый металлокерамический материал по прочности приближаетс к чугуну, обладает повыщенной износостойкостью, химической стойкостью и морозоустойчивостью .The proposed cermet material is close in strength to cast iron, has increased wear resistance, chemical resistance and frost resistance.
