A MONTE-CARLO SIMULATION OF THE ELECTRODEPOSITION PROCESS

Nucleation, grain growth, texture formation, and porosity formation in the electro-deposition process has been simulated with a Monte-Carlo method. In the simulation, a two-dimensional hexagonal lattice containing 12000 lattice sites are used to map the microstructure at the cross section of deposit. The criterion for grain growth is based on the energy state of the lattice site which is set by counting the interactions between the site and its nearest neighbors. This model can be used to obtain information of how the deposition rate affects the microstructure and porosity. The texture formation during the deposition process is modeled by taking surface energy anisotropy and deposition rate into account.
