RESUMO

Surface growth is an area whose methods apply to many systems on nature. On this work we review the growth process, with emphasis on the general growth relations, such as the KPZ equation and on the critical exponents universality. As a practical example we study a model where a corrosive liquid acts over a solid. Our main contribution is shown on chapter 3 where we calculate the velocity-velocity correlation functions of this model. We also obtain a new scale relation for the correlation time, with a new exponent ?.
