Установлено, что давление интенсифицирует химическое взаимодействие основных компонентов связок кобальта и В-13 с алмазом. Наблюдаются активное растворение алмаза в кобальте и взаимодействие с твердым раствором на основе α-Fe с образованием карбидов железа Fe3C (В-13). В области контакта алмаз–связка это активное химическое взаимодействие приводит к охрупчиванию связки и появлению трещин при изготовлении сколов. Добавка алмазного порошка АМ 14/10 к связке V-21 и спекание при 860 °С в течение 9 мин не приводит к изменению параметров твердого раствора на основе железа, т.е. химическое взаимодействие связка−алмаз идет значительно медленнее и охрупчивания контактной зоны связка−алмаз не происходит.</p></abstract><trans-abstract xml:lang="en"><p>The study of chemical interactions between the components of the three types of bundles with different chemical compositions based on Co, Fe (V-21), as well as copper and nickel (B-13) in the process of manufacturing a diamond tools by hot pressing.

Observed active dissolution of diamond in cobalt and inter- action with the solid solution based on α-Fe to form iron carbides Fe3C (B-13). In the contact-bond diamond is the active chemical interaction leads to embrittlement and cracking ligament in the manufacture of chips. The addition of diamond powder AM 14/10 to a bunch of V-21 and sintering at 860 °C for 9 min does not change the parameters of a solid solution of iron-based, that is, chemical interaction bunch-diamond is much slower and brittle contact zone ligament-diamond happens.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>связка алмазного инструмента</kwd><kwd>твердый раствор</kwd><kwd>химическое взаимодействие</kwd><kwd>горячее спекание</kwd></kwd-group><kwd-group xml:lang="en"><kwd>a bunch of diamond tools</kwd><kwd>solid solution</kwd><kwd>chemical interaction</kwd><kwd>hot sintering</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Young B. // Industrial diamond review. 1966.
