Hull cell modelling in alloy plating

Q. Dear sir,

I would like to know whether any mathematical modeling model is proposed for alloy plating based on Hull cell.

A. I am not really sure what you are asking, but I suspect you have been asked to use a Hull cell to determine the plating characteristics of an alloy system. A Hull Cell can be mathematically modelled as the local current density on the working electrode is related to the geometry of it (the working electrode) relative to the auxillary electrode. However, when plating an alloy, its composition will be dependent on the applied current density. Therefore, by using a Hull cell, you can controllably alter the alloy composition across the working electrode surface. The composition can therefore be modelled once you know your operating parameters and the properties of the alloy.
