Позорная война рф против Украины

Начата 20 февраля 2014 и полномасштабно продолжена 24 февраля 2022 года. С первых же минут рф ведет ее с нарушением законов и правил войны, захватывает атомные станции, уничтожает бомбардировками мирное население и объекты критической инфраструктуры. Правители и армия рф - военные преступники. Все, кто платит им налоги или оказывают какую-либо поддержку - пособники терроризма. Народ Украины вас никогда не простит и ничего не забудет.

Abstract
The process of producing by mechanical alloying method composite powders based on FeMoNiCrB amorphizing alloy with additives of refractory compounds (ZrB2, (Ti,Cr)C and FeTiO3) by processing a mixture of powder components in planetary mill “Activator 2SL” was studied. It was found that after 1.5 h of processing its products are homogeneous conglomerates with average particle size, depending on the composition of composite powders, which was 23 μm in the case of FeMoNiCrB + ZrB2, 15 μm in the case of FeMoNiCrB+(Ti, Cr)C, and 25 μm in the case of FeMoNiCrB + FeTiO3. XRD analysis results reveal formation of an amorphous-nanocrystalline structure in the produced composite powders, which consists of Fe(Ni, Cr), Mo2FeB2 solid solution and disperse phase of additives of refractory compounds (ZrB2, (Ti, Cr)C and FeTiO3) with indications of certain interphase interaction of FeMoNiCrB and (Ti, Cr)C. Here, the amorphous phase appears as a result of the process of mechanical alloying. The values of measured microhardness in the composite powders were as follows: FeMoNiCrB + ZrB2 – 6.2±1.6 MPa, FeMoNiCrB + (Ti, Cr)C – 5.5±1.1 MPa, FeMoNiCrB‒FeTiO3 – 5.1±0.7 MPa. For application in thermal spraying of coatings with an amorphous structure, the produced composite powders from mechanical alloying products are used to form conglomerate powders with particle size and degree of flowability, meeting the requirements of thermal spray coating technology.
