The article is aimed at finding regularities in the change of oleinic acid’s properties as a result RFH field’s influence and cavitation.

It is established that the protective properties of the solutions of oleinic acid in the conditions of influence of sulphurous anhydride and electrolyte depend not only on the processing mode of its RFH field or cavitational influence, but also on type of the corrosion environment. It is shown that the RFH field in contrast to cavitational processing practically doesn't change an interfacial angle of oleinic acid, and the most noticeable changes of the wettability occur by

using cavitational processing with termostatting. It is noted that the lack of a clear physical understanding of the mechanisms of influence on the properties of the various compositions both RFH field and cavitation doesn't allow to predict efficiency of any influence and demands further systematic experimental studies.
