Etching profiles in a two-dimensional cell are investigated using the thin-layer electrochemical experiment and the Monte Carlo simulation. The quasi-two-dimensional etching of an aluminium plate in NaCl aqueous solution is carried out in a Here-Shaw cell under an applied voltage. The time evolution of the etching profile on the aluminium plate is analysed by using digitized computer images. The transport of anions with the surface reaction is simulated using the extended multiparticle Monte Carlo method for ti-le diffusion-limited aggregation. It is shown that the etching profile can be mimicked by the simulation model. [References: 17]
