Figure 19 Pore depth ( x ) against weld length ( z ) position.
Pore depth was linearly dependent on the dissolution time.
In this case, not only the AAO growth pore depth can be monitored, but also a target pore depth can be set and the anodization process can be terminated when the projected pore depth reaches the set point.

b Linear fitting of AAO pore depth dependence on integral of stable anodization charge density.
Therefore, this linear relationship can be utilized to monitor AAO pore depth in real time.
In this case, the macropores were etched for several hours (depending on the required pore depth).
The pore depth decreased from approximately 4 to 3.6 μm with chemical etching for 20 min.
