The object of investigation – a phenomenon of phase formation of metals being electrodeposited through a stage of liquid state. The aim of work – experimental verification of the validity of the discovered phenomenon of phase formation of metals being electrodeposited through a stage of liquid state. Methods of investigation – scanning electron microscopy, hydrostatic weighing, microstructure analysis. As the results of the completed scientific research work the effects of the increase of density and the decrease of porosity of metals being electrodeposited at the external force influence perpendicular to the crystallization front were found. It was discovered, that porous structure of electrodeposited metal possesses all typical features of porous structure of metal solidified from liquid state in saturated hydrogen environment, namely – identity of orientation and form of pores, presence of the effect of pores coagulation, termination of pores growth and initiation of new pores during the whole period of crystallization at electrodeposition. The obtained results prove the validity of the phenomenon of phase formation of metals being electrodeposited through a stage of liquid state. The results of the work bring fundamental changes to the existing conception of phase formation of metals during their electrochemical deposition and determine new directions for obtaining of electrocoatings with enhanced chemical and mechanical properties. The fields of application of the results of scientific research work: C 25.6 – processing of metals and applying of coating on metals; mechanical processing of metal items; C 33.2 – installation and assembling of machines and equipment; E 38.2 – processing and removal of waste.
