Orientation ordering of boundary layers and lubricity of oils
The analysis of the computer model of the adsorption of oil molecules on friction surfaces favoring their orientation shows that orienting coatings provide a good structural ordering of molecules in the boundary layer while amorphous coatings produce no orienting effect on the layer. The results of tribotesting of some carbon coatings on steel surfaces in the model lubricants prove that the coatings producing a good orienting effect possess the best lubricity
