Tribological modification of metal counterface by rubber

Sulphur vulcanizates of styrene-budadiene rubber (SBR) filled with 80 phr of silica were rubbed extensively against iron Armco or magnesium alloy (AZ 31), and chemical modification of the surface layer of metals studied. Secondary Ion Mass Spectrometer (s-SIMS) spectra revealed fragments containing...

Summary:Sulphur vulcanizates of styrene-budadiene rubber (SBR) filled with 80 phr of silica were rubbed extensively against iron Armco or magnesium alloy (AZ 31), and chemical modification of the surface layer of metals studied. Secondary Ion Mass Spectrometer (s-SIMS) spectra revealed fragments containing sulphur. Also Raman spectra, obtained with the surface focused confocal microscope, apart metal oxides, contained absorption peaks indicated on metal sulfides and sulfates. Depth of the modification, calculated from Atomic Force Microscope profiles of ion-etched samples (s-SIMS depth profiling) reached several tens of nanometers, what corresponds to several monolayers. The thickness of modified layer was higher for magnesium alloy, due to its higher electronegative character in comparison to iron.
