| Abstract: | Low angle X ray diffraction has been applied to analyze the structure of stearic acid LB films and self grown surface adsorbed films of aluminium product metalworking lubricants. The results show that LB films exhibit a good layer like ordered structure in the normal direction of film carrying surface, while in the tangential direction, they do not show a cyclically ordered molecular arrangement; as for the self grown surface adsorbed films of aluminium sheet and strip metalworking lubricants, their molecules are orderly arranged to certain degree in both the tangential and the normal directions of film carrying surface, and they have a short range ordered structure. Moreover, the better the orientation of normal molecules is, the higher the oil film strength is, and the smaller the friction factor is. |
