Abstract

In this paper we build an experimental apparatus to measure the reflectivity and temperature of the foil in different conditions. The experimental results show that the growth of oxide film can be divided into 3 stages which corresponding to logarithmic, linear and parabolic rate law. A mathematical model is introduced to explain the phenomena observed in experiment. Numeral calculations are made for 30CrMnSi steel while cw-laser wavelength is 1.07μm. The numerical solutions are in agreement with the experimental data.
