This study investigates the elemental composition and surface morphol. of solid tribochem. films formed on steel surfaces. The reversible addition-fragmentation chain transfer (RAFT) method was used to synthesize nine different metal-free polymers, which were blended into com. base oils. The polymers were either homopolymers of dodecyl methacrylate and ethylhexyl methacrylate or were co-polymers of these monomers with six polar monomers. After tribol. testing at 100°C using the ball-on-flat geometry, the resulting tribochem. films were imaged using SEM and optical microscopy. The resulting tribochem. films have thicknesses around 50-100 nm. Two of the films corresponding to small (P1-imidazole-containing copolymer) and large (P3-less polar homopolymer) wear were cross-sectioned using focused ion beam and analyzed for elemental composition using energy-dispersive X-Ray mapping. Oxygen and nitrogen enrichment was observed, consistent with the relative chem. composition of the precursor polymers. Transmission electron microscopy evidence suggests that at the worn surface, some organic elements penetrate or are mixed into the steel substrate giving an interlocking appearance. The two samples examined with TEM showed that P1 tribofilm is diffused or mixed with the steel substrate more so than P3, suggesting a stronger affinity and contact during tribofilm formation.
