Abstract

This paper presents the XRD and SEM analysis results of molybdenum carbide powder synthesized by DC arc discharge plasma in air. The regularities of the phase composition distribution in the reaction zone are revealed. It was determined that in the arcing zone the initial molybdenum is completely processed, the hexagonal molybdenum carbide has the greatest yield. As a distance from the arcing zone increases, the fraction of cubic molybdenum increases, orthorhombic molybdenum carbide and graphite phases decreases. According to SEM data, the features of element composition and morphological types of samples collected from different parts of the reaction zone were revealed.
