Description
Summary:The article proposes a method of magnetron vacuum deposition of tungsten carbide coatings on spherical hydride granules. The article also illustrates the features of the microstructure and the uniformity of the resulting coating. The effect of heat treatment on the oxygen content in the near-surface areas of titanium hydride coated with tungsten carbide is investigated. The features of the coating structure were studied using by scanning electron microscopy (SEM) with a built-in energy dispersion spectrometer. Comparative data on thermal oxidation of uncoated spherical granules and granules coated with tungsten carbide are presented.
