Information is given on the study of the process of obtaining two-layer copper permeable powder-fiber materials, based on the activation of the fiber sintering by finely dispersed powder particles process, which are also used to form a thin filter layer. It has been confirmed that the activation of the fiber sintering process by finely dispersed powder particles ensures high-quality consolidation of metal fibers. The optimal ratios between copper fibers, polyvinyl alcohol used for applying fine particles to the fibers, and copper powder have been determined.

The results of testing a nozzle with a zero angle of attack for obtaining atomized metal powders are presented, which indicate its increased overhaul life, a satisfactory yield of fine fraction powders with a good spherical powder shape.
