Description

Целью изобретени   вл етс  замена кобальта или других дорогосто щих металлов более дешевым цементирующим материалом, например, тончайщим (пор дка 320 меш) стекл нным порошком.The aim of the invention is to replace cobalt or other expensive metals with a cheaper cement material, for example, a thinnest (about 320 mesh) glass powder.

С целью получени  пористых изделий, в смесь порошков металла и стекла, подлежащую прессованию, ввод т органические добавки, выгорающие или улетучивающиес  при спекании.In order to obtain porous products, organic additives that burn out or volatilize during sintering are introduced into the mixture of metal and glass powders to be pressed.

Подбор состава стекла производ т в зависимости от металла, пороцюк которого подвергают спеканию, и назначени  сплава. Стекла могут быть подобраны в широком интервале с температурой разм гчени  400- 1800 и с различной адгезионной способностью.The selection of the composition of the glass is made depending on the metal, the porosyuk of which is subjected to sintering, and the purpose of the alloy. Glasses can be selected in a wide range with a softening temperature of 400-1800 and with different adhesion.

Температура спекани  зависит от спекаемых компонентов и может колебатьс  в пределах 400-1800° (а в случае карбидов и выше). Дл  предупреждени  окислени  металла в шихту можно вводить небольшие летучие добавки: аммиак и другие. Обжиг протекает в восстановительной среде.The sintering temperature depends on the components to be sintered and can vary from 400 to 1800 ° C (and in the case of carbides and above). To prevent metal oxidation, small volatile additives can be introduced into the mixture: ammonia and others. Firing takes place in a reducing environment.
