Description

Дл промышленного производства Т;вердых сплавов примен ютс методы осаждени металла на поверхность зерен карбидов тугоплавких металлов.Methods of metal deposition on the surface of grains of carbides of refractory metals are used for industrial production of high alloys.

Предлагаемый способ из10товлени т:вер(дых оплавов за-хлючаетс IB том, что шихту дл этих сплавов составл ют, ввод в порошкообразную смесь частиц твердых составл ющих (карбидов, нитридов и вр.) св зуюш,ие металлы в виде раCTBOipoB карбонильных соединений этих металлов. Предлагаемый способ отличаетс еще тем, что в качестве растворител дл карбонильных соединений, вводимых п шихту, используют растворы каучука , с целью предохранени частицв шихте от окислени и улучшени УСЛОВИЙ СПбкаЕи твердого сплава.The proposed method of isolating t: ver (hot melts implies IB, that the mixture for these alloys is made by injecting powdered carbonyl compounds into the powder mixture of solid components (carbides, nitrides and temp.) Metals. The proposed method also differs in the fact that rubber solutions are used as a solvent for carbonyl compounds introduced into the mixture in order to protect the particles in the mixture from oxidation and to improve the conditions of hard alloy.

Введение карбонилов осушест .вл етс с помошью растворителей , например, раствОров каучука в бензине.The introduction of carbonyls is dried with the help of solvents, for example, rubber solutions in gasoline.

Способ предоставл ет возможность использовать полоЖИтельные качества ов зуюших металлов.The method makes it possible to use the positive qualities of the metals of interest.

Claims

1. A method for manufacturing solid metal-ceramic-metal alloys, which is the fact that the iijHXTY for these Alloys are composed of INPUTING a vapor-like mixture of particles of solid composition or carbides, nitrias and others.) bonding metals (one or several) In the form of solutions of the carbonyl compounds of these metals, followed by precipitation of the bonding of their metals on the surface, of solid particles during the decomposition of carbonyls.

2. The implementation of the method according to claim 1 is distinguished, and also with that, as a solvent for carbonyl compounds introduced into the mixture, rubber solutions are used to protect the particles in the mixture from oxidation and to improve the conditions of the solid splash.
