ABSTRACT

The aim of the work was the experimental verification of the validity of the phenomenon of phase formation through a stage of liquid state in metals being electrodeposited. It is found that saturation of metal by hydrogen during electrodeposition is one of the major factors determining its porosity. Growth of porosity of metal with the increase of its saturation by hydrogen during electrodeposition is discovered. It is found that polymorphous metal being electrodeposited crystallizes in the form of intermediate modification, which is identical to the one of polymorphous metal solidified from liquid state in saturated hydrogen environment. Formation of porous structure in metal being electrodeposited, which possesses all typical features of porous structure of metal solidified from liquid state in saturated hydrogen environment, is discovered. The obtained results prove the validity of the phenomenon of phase formation through a stage of liquid state in metals being electrodeposited.
