Protective oil molecular film on metal surfaces: Method for determining quality

A method for assessing the quality of a protective oil film by determining the contact angle and oil absorption capacity of the surface is presented. This method allows determining the efficiency of using the proposed surfactant based on an organofluorine compound. The use of this substance increases the contact angle and oil absorption capacity of the surface, which can affect the quality of friction pairs. Collection, processing and analysis of the results of laboratory experiments and determination of the main properties of the treated surface allow us to speak about the high efficiency of the proposed composition. The optimal concentration of the substance in the reference oil and the holding time for the formation of a stable protective oil film were experimentally determined. In the future, it is planned to develop a method and conduct laboratory tests on friction machines using the proposed composition.
