Abstract
Results of investigations of spherical and non-spherical particles of tungsten carbides WC—W2C produced by the method of thermal centrifugal spraying are described. Chemical and energy-dispersive spectral analyses of the particles were carried out. Wear resistance of clad samples was investigated. It was shown that part of the non-spherical particles can be used for deposition of composite coatings.
