В работе электроэрозионным диспергированием сплава Т5К10 в масле получен порошок, который был нанесен на заготовки из стали 35 методом электроискрового легирования нелокализованным электродом, исследованы состав, структура и свойства полученных покрытий. Определены химический и фазовый составы и микроструктура полученных частиц. Установлено, что при электроэрозионном диспергировании в образующихся частицах порошка происходит полное растворение исходного карбида вольфрама в кубическом карбиде (Ti,W)C. Исследования кинетики массопереноса при электроискровом легировании нелокализованным электродом показали, что полученный порошок наносится вместе со стальными гранулами со скоростью 1,9-2,6 мг/(см2×мин). Полученные покрытия состоят из вольфрам-содержащих и железосодержащих фаз, элементы которых равномерно распределены по глубине покрытия. Концентрация элементов W, Ti, Co в покрытиях зависит от соотношения масс порошка и стальных гранул в наносимом порошке. Испытания показали, что, благодаря высокой концентрации легирующих элементов в покрытиях, они обладают высокой твердостью (6,4 ГПа-9,2 ГПа) и пониженной скоростью износа (0,13×105-0,39×105 мм3/Нм) по сравнению с исходной сталью 35 (2,6 ГПа и 2,47×105-2,65×105 мм3/Нм соответственно).

“…At this point, researchers are making intense efforts to improve the properties of the material. In service conditions where the use of steel is inevitable, improving the surface properties instead of improving the properties of the entire material appears to be a very economical engineering approach [8][9][10][11].…”

In this study, Fe-Mo-B-based hardfacing electrodes containing different amounts of Mo were coated on an AISI 1020 steel substrate using the electric arc welding method. The findings show that molybdenum is highly effective on the microstructure and minor changes in the coating composition affect the phases and morphological properties. In the hardness tests, an increase of 73% was achieved in the Fe14Mo2B4-based hardfacing coating, compared to the base material, and a 30% increase was achieved, compared to the Fe16B4-based coating. The highest hardness value was measured as 56.4 HRC and the highest phase hardness was measured as 3228 HV in the FeMo2B4 phase. The lowest wear rate was measured in the Fe14Mo2B4-based coating. The wear rate of the Fe14Mo2B4-based coating was 8.1 times lower than that of the substrate material and 4.7 times lower than that of the Fe16B4-based coating. According to corrosion test results, the highest corrosion resistance was obtained in the Fe16B4-based coating. The current density value of the Fe16B4-based coating was measured to be 13.6 times lower than that of the substrate material.

“…Well-known methods for modifying the surface of parts and tools include PVD [6][7][8][9][10][11][12], CVD [13][14][15], and directed energy deposition (DED) [16]. In addition, known methods include (1) self-lubricating coatings obtained by laser additive manufacturing technology for friction reduction [17]; (2) textured coatings operating without lubrication and obtained by laser technologies [18]; (3) composite ceramic coatings obtained by the method of electric arc surfacing [19]; and (4) plasma electrolytic oxidation, also called micro-arc oxidation [20]. These methods are widely used in industry but have a number of advantages and limitations.…”

In this work, the features of the phase composition, structures, and properties of coatings obtained on a high-speed steel substrate (steel R6M5) were studied. The coatings were prepared using the ESA method (electro-spark alloying). Electrode materials prepared through self-propagating high-temperature synthesis (SHS) based on (Ti-B-Fe)xAlN with the addition of nanosized AlN particles in the amount of x = 0.5, 10, 15 wt % were used as electrodes. The structure, phase composition, and physical and mechanical properties of the SHS electrode materials are reported. It was found that the coatings inherited the structure of the SHS electrode material and formed two characteristic zones for x = 0 and three zones for x = 5, 10, 15. The surface hardness of the substrate made of the high-speed steel R6M5 with the developed coatings was found to increase up to five times compared to the uncoated substrate. It was found that the wear resistance of the samples with the coating was four to six times higher than that of uncoated samples.
