Study of Phase Composition Homogeneity in Depth of Tungsten Carbide Ceramics Produced by Spark Plasma Sintering

Tungsten carbide (WC) ceramics obtained by spark plasma sintering were investigated by layer-by-layer X-ray diffraction analysis. It was found that the phase composition of WC ceramics varies with the distance from the sample surface.The study was supported by the Russian Foundation for Basic Research under Scientific Project №20-33-90214

STUDY OF THE PHASE CONTENT HOMOGENEITY OF CERAMICS OBTAINED BY SPARK PLASMA SINTERING OF POWDERWC + 10 %Co

The phase content of ceramic samples WC + 10 % Co was studied. Samples were obtained in different sintering modes. The isothermal holding in the sintering process did not affect on the depth distribution of the main phases.Исследован фазовый состав керамических образцов, полученных в разных режимах спекания порошка WC+10 %Co. Проведение изотермической выдержки в процессе спекания не повлияло на распределение основных фаз по глубине образца.Работа выполнена при финансовой поддержке РНФ в рамках гранта № 18-73-10177

Influence of the Effect of Carbon Impurity on the Phase Composition of Ceramics Produced by the Method of Electric Pulse Plasma Sintering

Carbon impurity effect during spark plasma sintering due to the sample and graphite mold surfaces contact can lead to a changes in the phase composition of the sintered ceramics. The carbon influence effect on the phase composition in ceramics based on Si3N4 with Y2O3-Al2O3 addition is observed.Исследование выполнено при финансовой поддержке РФФИ в рамках научного проекта № 19-33-60084
