Theory, Production Technology, and Properties of Powders and Fibers


The electroerosion disintegration of a manganese-containing Sormait type alloy in water yields powders of spherical particle shape. A coarse (>40-Μm) fraction of such a powder consists mainly of hollow particles, which are the most suitable for the flame-spray deposition of coatings. The particles of the powder have a homogeneous fine-grained structure differing radically from that of the starting alloy, and surpass the latter in microhardness. The powder is passivated by Fe3O4 films which increase its resistance to attack by corrosive environments. EE powders may find application for the deposition of protective coatings.
