Loss of current density in sulfuric acid anodizing plant
Please,
What are the most likely causes of a serious loss of current density in a sulfuric acid anodizing plant?

I am not sure that I understand the real question. Line loss results from corroded connections, corroded buss bars, too small wire or bar, inadequate sized racks to carry the load and ? James Watts- Navarre, Florida Perhaps more data would suggest other answers but on the face of the question it is the nature of the system that as the oxide builds the resistance increases, then if you do not increase the voltage, the current falls off. This happens rapidly in the case of hard coat (high current density) and slower in the case of conventional (Type II) anodizing. Come back to us with more data and maybe we can suggest other answers.  Robert H Probert Robert H Probert Technical Services  Garner, North Carolina  |
