“…The maximum and minimum limiting currents for opposite positions of a horizontal surface during electrodeposition of copper differ threefold [10]. The limiting currents of the triiodide reduction in the same conditions depend on the electrolyte composition and differ by 2-2.9 times [12]. Altering the vertical electrode position during the anodic electropolishing of copper to a horizontal, directed downward, makes the limiting current rise by 1.5 times [14].…”

Measurements of the copper corrosion rate in 0.5 M H 2 SO 4 as a function of the tilt angle of the corroding electrode surface in the gravitational field show that the downward flux of natural convection (NC), which arises during corrosion, effects the process similarly to NC that arises when electrochemical reactions proceed in a diffusion kinetics mode. The corrosion rate of a horizontal face-down electrode is 2.3 times that when facing up. Without NC, when a horizontal face-up copper electrode is in a recess, its corrosion rate is defined by the oxygen diffusion current and is 12-28 times as small as that with NC next to its surface.

“…The limiting diffusion current of the cathodic process is minimum on a cathode facing down. The current alters with the tilt angle and is maximum on a cathode whose plane is facing up [9][10][11][12]. With the anodic process the situation is exactly the opposite: the limiting diffusion current is maximum on an anode facing down [9,13,14].…”
