通过考察极性化合物的吸附能力，研究了横向粗糙度下吸附膜的减摩效果。在吸附膜由硬脂酸或聚甲基丙烯酸酯形成的情况下，在低速条件下摩擦逐渐减小。这可能是因为减摩效果根据吸附能力和官能团的数量而变化。结果表明，摩擦表面的减摩作用不仅可以通过横向粗糙度产生的微观弹流效应来解释，而且还可以通过与吸附膜形成状态有关的其它承载效应来解释。
The friction-reducing effect of an adsorbed film at transverse roughness was investigated by focusing on the adsorption ability of polar compounds. Gradual reduction in friction under the low speed condition in case of the adsorbed film is formed from stearic acid or polymethacrylate. This is probably because the friction-reducing effect varied according to the adsorption ability and the number of the functional group. The results implied that the friction-reducing effect could be explained not only by the micro-EHL effect derived from transverse roughness but also by some other load-bearing effect, which depends on the formation state of the adsorbed film.
