Pure metals
Some reflections on a model to predict the erosion rate of the passive film on pure metals
... Based on the work of Tirupataiah, previous work involving the current investigators [3] introduced an erosion model for passive layers of metals. The basic assumption was that the rebound velocity is explicitly ...
