Electrochemical Phase Formation in Metals under Low Force: Part 1. Increase in the Density of Electrodeposits

Reorientation of grain crystal lattices in metals/alloys during electrocrystallisation under the action of force

“…Copper and nickel-doped copper alloys were electrocrystallised under the action of centrifugal force in the installation, whose schematic diagram is described in Girin. 11 The installation provided action on the process of copper sample electrocrystallisation by a centrifugal force proportional to the acceleration kg, where k is the overload factor. The value of the centrifugal force was changed gradually, by changing the number of the rotor revolutions per minute from 0 to 3000 rpm, which corresponded to an acceleration of 1, 35, 140, 314, 558, 872 and 1256 g.…”

“…10 In addition, many scientific facts have accumulated to date, which are difficult to satisfactorily explain on the basis of the existing ideas about the phase formation in electrocrystallised metals/alloys (e.g. an increase in the density of metals electrocrystallised under the action of small force exerted perpendicular to the crystallisation front 11 ; the wave-like flow of the surface layers of electrocrystallising metals under small force exerted parallel to the crystallisation front 12 ; change in the form of deposits of electrocrystallising metals under small force acting parallel to the crystallisation front, 13 etc.). Therefore, the existing ideas about the phase formation in electrocrystallised metals/ alloys require clarification and development on an alternative platform, with putting forward and implementing new ideas and approaches.…”
