Abstract

A model to predict the erosion rate of the passive films on metals is proposed. The model investigates the effect of eroded particles on a metal on which a passive (oxide) film has formed. To date, many of the existing erosion models have concentrated on normal angle erosion of the oxide layer. This new approach considers the effect of oblique impacts on the oxide layer and the effect of its thickness on the amount of metal and oxide layer removal. The model is then tested by comparision to previous experimental work.
