The deposition rate of the metal is found using Faraday s law. 

Taking into account the area of the cathode available for metal deposition, that is (1 -0) for non-conducting particles the current density is related to the overpotential by the Tafel equation  

The constants k, v0 and B depend on the type of composite considered and have to be determined from experimental data using Eq. (5). A plot of 

Guglielmi validated his model for Ni-Ti02 and Ni-SiC composite deposition. From the obtained values for k it was found using Eq. (1) that 0 crand it was concluded that the strong adsorption step is rate determining. The model was also successful in describing the variation of the particle composite content with the particle bath concentration and current density of several other composites.57,59,60 66 79 84 For example,

It was not until 1987, before a second model on electrocodeposition was published by Buelens [37, 58], From experimental observations on the codeposition of particles on a rotating disk electrode (RDE) as a function of current density, rotation speed and bath composition, that could not be explained by Guglielmi, she suggested that a particle will only be incorporated into the deposit if a certain amount of the adsorbed ions on the particle surface is reduced. This is one possible way to account for the field-assisted adsorption, held responsible for the transition between loosely and strongly adsorbed particles in the model of Guglielmi. This proposition yields the probability P(k/K,i) for the incorporation of a particle based on the reduction of k out of K ions, bound to its surface, at current density i...
