Связки получали методом композиционной пайки: порошковые компоненты смешивали с органическим связующим и наносили на стальную основу. Спекание проводили при температурах 820–1100 °С. Строение металлических связок исследовали методами рентгенодифракционного и микрорентгеноспектрального анализа. Кроме того, измеряли микротвердость структурных составляющих и макротвердость связок. Установлено, что с увеличением содержания олова твердость металлических связок линейно возрастает вследствие повышения количества твердых интерметаллидных фаз в их структуре. Для связок Sn–Cu–Co–W определено оптимальное содержание олова, обеспечивающее высокую твердость (96–98 HRB) и отсутствие в их структуре легкоплавких высокооловянистых интерметаллидов.</p></abstract><trans-abstract xml:lang="en"><p>The influence of the tin content on the structure and hardness of the Sn–Cu–Co and Sn–Cu–Co–W alloys, which are applied as bonds of diamond-abrasive tools, is investigated. Bonds were prepared by the compositional brazing: powder components were mixed with organic bond and deposited on a steel base. Sintering was performed at 820–1100 °C. The structure of metallic binders was investigated by the X-ray diffraction and electron probe microanalyses. In addition, microhardness of structural components and macrohardness of bonds were measured. It is established that the hardness of tin bonds linearly increases as the tin content increases due to an increase in amount of solid intermetallic phases in their structure. The optimal tin content, which provides high hardness (96–98 HRB) and absence of low-melting high-tin intermetallic compounds in the bond structure, is determined for the Sn–Cu–Co–W bonds.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>алмазно-абразивный инструмент</kwd><kwd>металлическая связка</kwd><kwd>композиционная пайка</kwd><kwd>олово</kwd><kwd>интерметаллиды</kwd><kwd>твердость.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>diamond-abrasive tool</kwd><kwd>metal bond</kwd><kwd>compositional brazing</kwd><kwd>tin</kwd><kwd>intermetallic compounds</kwd><kwd>hardness</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">Konstanty J.
