Influence of additives and their molecular structure on the static and dynamic wetting of oil on steel at room temperature

The effect of additives, their type and structure on the wetting of oil has received little attention so far and is thus poorly understood. This is despite the fact that a number of additives are present in every lubricating oil. Here, we report on the influence of the addition of some simple organic friction modifiers, namely, fatty acids, amides, alcohols and amines, on the static and dynamic (i.e., the advancing and receding contact angles,...
