Abstract
This article describes the basic methods of production of specialized metal powders for laser additive
manufacturing. The brief overview of the principles of the atomizers, highlighting major shortcomings.
an alternative method of production of specialized metal powder have been proposed for addition of
laser technology - plasma treatment. The technique of the experiment the plasma treatment of the brand
PMS-1 metal powder. According to the results of the research conclusions were drawn about the
possibility of applying plasma processing to optimize the shape of the powder particles.
