    Abstract

    The amount of hydrogen in the steel specimens obtained from a cyclic contact test was investigated in order to understand the process of permeation of hydrogen into the steel in rolling contact. Cyclic contact test with slip was conducted in a sealed chamber, in which cyclic stress, slip and surrounding gas were controlled. The amount of hydrogen in the steel after the test was analysed by secondary ion mass spectrometry. It was found that the amount of permeated hydrogen after the test performed in hydrogen gas was not greater than those after the tests in dry air and vacuum condition. It was also found that the oxide film and the hydroxide film were formed on the contact area after the test in hydrogen gas. These results suggested that the oxide film and the hydroxide film, formed in the process of cyclic contact with slip, prevented hydrogen from permeating into the steel.
