Ihor Kolesnyk

Abstract: The installation scheme for sintering metal powder materials in a constant magnetic field is presented. The principal possibility to significantly reduce the duration of the sintering process for metal powder products is demonstrated. The method is based on the phenomenon of anomalous penetration of electromagnetic radiation into the depth of the sintering product. Comparison between the proposed method and most common technology of powder metallurgy as sintering in a muffle furnace has been shown. The presented technology allows sintering of electrically conductive powder materials at temperatures below the temperature in the case of sintering in a muffle furnace. The duration of the sintering process using the effect of anomalous radiation penetration has decreased several times in comparison with the traditional technology. The obtained micrographs of sintered powder blanks made it possible to confirm the effectiveness and feasibility of using the presented method. The totality of the obtained research results confirms the promise of studying the effects of anomalous radiation penetration during sintering of metal powders.
