The phrase "a higher anodization voltage" is correct and usable in written English.
It can be used in contexts related to electrochemistry or materials science, particularly when discussing the process of anodization and its parameters.
Example: "To achieve a thicker oxide layer, we need to apply a higher anodization voltage during the process."
Alternatives: "an increased anodization voltage" or "a greater anodization voltage".
Higher anodization voltage leads to higher anodization current.
The new regime corresponds to the stage with a stable voltage during constant-current anodization process, accompanied by high anodization voltage (Ua, 135 183 V) and current density (Ja, 300 500 A m 2) which facilitate the high speed growth of long-range ordered porous AAO films.
Since the pitch of AAM is proportional to the applied anodization potential, high anodization voltage need to be applied to get large-pitch AAM; as a result, the anodization electrolyte should be weak acid to avoid chip burning from occurring.
The high anodization voltage also enables the formation of some randomly orientated nanotubes and defects [23], which further enhance the light scattering in LTNA.
In addition, the oxygen vacancies in the structure of NAAMs fabricated in malonic acid are lower than that of those produced in oxalic acid because of the reduction in the oxygen evolution, tensile stress and electrostriction pressure at high anodization voltage.
Meanwhile, the addition of LA and the use of an aged electrolyte can prevent the anodic breakdown and the oxide burning under too large a current density at high anodization voltages [19, 20].
They also investigated the influence of the quality of titanium film and high anodization voltages (up to 200 V) on the morphology of TiO2 NTAs.
A high anodization current reflects a high pore etching rate and a fast pore formation.
In this article, the influence of crystal structures of multiphase electrodes during a high voltage anodization process was demonstrated.
By means of an ellipsometry-based optical characterization combined with ESEM picture analysis, we have shown that the pore-widening rate of NAA is higher when obtained with a smaller anodization voltage.
