Surface roughness anodization

For example, the small tolerance and low surface roughness of the plate in manufacture are critical for assuring the high electrical contact conductivity, low fluid flow resistance, and low water holdup to meet performance require-menfs of fhe plates. Moreover, to play the role of removing generated water in the cathode side—particularly to avoid flooding when fhe current density is high, the surface of the cathode plate may need hydrophobicity [11] so as to better adjust hydrophobic and hydrophilic properties of plate materials in cathode and anode plates. This area needs further study. 

As discussed earlier, electrochemical dissolution proceeds under dynamic conditions when the applied anode potential is relatively low that is, the process is dominated by electrochemical reactions, and potential and current obey Ohm s law, as expressed in Equation 10.9. Under these conditions, surface planarization can be achieved by electrochemical dissolution if the interelectrode distance and anode surface roughness have the same order of magnitude. As illustrated in Fig. 10.7, the distance (f) between the anode and...
