Comparative Study on the Cyclic Corrosion Test of Rail Steel U68CuCr and U75V

Abstract:

A further investigation into the determination of corrosion resistance behavior has been carried out through a series of cyclic corrosion tests in order to comparatively study the corrosion rates of rail steel U68CuCr and U75V under different cycle conditions. The results indicate that U68CuCr possesses better corrosion resistance than U75V. According to macroscopic view, colors of U68CuCr surfaces are all lighter than those of U75V in the same group. Moreover, the grains at the rust layer of U68CuCr specimens show much finer and denser microstructure than U75V. Besides, cracks on the rust layer of U75V specimens are found.
