Characterization of organic monolayers on the surface of aluminum in the process of thermal treatment

The FTIR work was supported by measuring absolute surface carbon content using direct combustion method and measurement of the wettability by water. As expected the thermal degradation of the residual rolling oil caused a decrease in the carbon content of the film and an increase in the wettability of surface. However, it was also found that there is a direct proportionality between the cosine of contact angle of water and the absolute amount of carbon on the surface in the process of thermal treatment.
