Обнаружено, что добавки Ni3B B обеспечивают формирование многофазной микрогетерогенной структуры материала матрично-наполненного типа, состоящей из хромистой стали и твердых включений сложных карбидов хрома и железа (таких, как Ме3С, Me7C3 , Me23C6 ) и боридов (FeB, Fe2B), повышающих микротвердость твердой составляющей от 8,34 до 11,65 ГПа. Также выявлено, что увеличение содержания легирующей добавки от 3,5 до 8,7 мас.% улучшает устойчивость материала к абразивному изнашиванию (от 6,9 до 12,2 км/мм) и снижает твердость (от 75 до 68 HRA) и прочность на изгиб (от 1560 до 844 МПа). Методом оптической профилометрии изучены топографические особенности морфологии изношенных поверхностей для оценки глубины и локального развития процесса разрушения поверхности образцов с использованием стандартизированных параметров шероховатости, вычисленных из 2D- и 3D-профилей. Установлено, что усредненные параметры шероховатости поверхности для материалов, легированных боридом никеля, составляют, мкм: Ra = 0,44÷0,6, Rz = 0,49÷1,2, Rp = 0,26÷0,56, а для базового материала: Ra = 1,860, Rz = 0,813, Rp = = 3,356 мкм. Показано, что перспективными составами, сочетающими требуемые физико-механические свойства и повышенную стойкость против абразивного изнашивания закрепленными частицами алмазного круга, являются материалы на основе системы Fe–35%ФХ800, содержащие 5,2–6,9 мас.% Ni3B.</p></abstract><trans-abstract xml:lang="en"><p>The study covers the effect of nickel boride (Ni3B) additives on phase-structure formation, physical and mechanical properties and resistance of iron – high-carbon ferrochrome powder (35 wt.%) to abrasive wear. It was found that Ni3B additives provide the formation of a multiphase, microheterogeneous structure of a matrix-filled material consisting of chromium steel and solid inclusions of complex chromium-iron carbides such as Ме3С, Me7C3 and Me23C6 and borides FeB, Fe2B that significantly increase the microhardness of solid phases from 8.34 to 11.65 GPa. It was also revealed that the increase in the content of a doping additive from 3.5 to 8.7 wt.% increases base material resistance to abrasion wear from 6.9 to 12.2 km/mm and decreases hardness from 75 to 68 HRA and bending strength from 1560 to 844 MPa. The method of optical profilometry was used to study the topographical features of worn surface morphology to estimate the depth and local development of wear on sample surfaces with standardized roughness parameters calculated based on 2D or 3D profiles. Average roughness parameters for each composition were found to be Ra = 0.44÷0.6, Rz = 0.49÷1.2 μm, and Rp = 0.26÷0.56 μm for materials doped with Ni3B, and Ra = 1.860 μm, Rz = 0.813 μm, Rp = 3.356 μm for the base material. It was shown that the promising compositions that combine acceptable physical and mechanical properties and improved abrasive wear resistance are materials based on the Fe–35%FeН800 system containing 5.2–6.9 wt.% of Ni3B.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>порошковые материалы</kwd><kwd>композит</kwd><kwd>абразивное изнашивание</kwd><kwd>износостойкость</kwd><kwd>железо</kwd><kwd>борид никеля</kwd><kwd>спекание</kwd><kwd>твердость</kwd><kwd>микротвердость</kwd><kwd>триботехнические свойства</kwd></kwd-group><kwd-group xml:lang="en"><kwd>powder materials</kwd><kwd>composite</kwd><kwd>abrasive wear</kwd><kwd>wear resistance</kwd><kwd>iron</kwd><kwd>nickel boride</kwd><kwd>sintering</kwd><kwd>hardness</kwd><kwd>microhardness</kwd><kwd>tribotechnical properties</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">Гарбер М.Е.
