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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
