Figure Lengend Snippet: IR spectra of PAO40-PAG-50%w (a) in static conditions under 5.4 N at several distances from the contact center and (b) under pure rolling dynamic conditions at U e = 0.18 m/s and w = 5.4 N. The line of red squares in the insets corresponds to the area considered for the IR spectra analysis, here 20 × 20 μm 2 . Each spectrum comes from one square.

Figure Lengend Snippet: IR spectra obtained in the contact center during the mapping of contact zone lubricated with PAO40-PAG at 50%w at w ≈ 5.4 N for U e = 0.18 m/s. The main peaks discussed in the text are indicated with black hooks. The inserts represent the mapping based on the u C–O–C stretching band. The black circle indicates the hertzian contact, and the black square shows the location of the considered IR spectra. The blue arrow represents the direction of the entrainment speed.
