Tribochemical Reaction of Benzene on Nascent Steel Surface and Effect of Temperature

Abstract

The effect of temperature on the adsorption of benzene on the nascent surface of steel was examined. Cutting tests were carried out under high vacuum condition. The components adsorbed onto or desorbed from the nascent surfaces formed by cutting were monitored by a quadrupole mass spectrometer. The adsorption rate of benzene decreased with increasing temperature whereas desorption rate of hydrogen and adsorption rate of water increased. It appeared that water from residual gas preferentially adsorbed onto the nascent surface to disturb benzene adsorption as the temperature increased where the water was decomposed to form hydrogen. In this study, it was found that the reaction of adsorption on mechanically formed nascent surfaces is affected by temperature. Adsorption activity of mechanically formed nascent surfaces was calculated.
