THE TRIBOCHEMICAL MODIFICATION OF THE SURFACE LAYER OF A POLYMER IN SLIDING CONTACT WITH ARMCO
Journal Title: Tribologia - Year 2010, Vol 233, Issue 5
Abstract
The degree of the tribochemical modification of contact surfaces in a polymer – metal friction pair, taking into account the transfer of iron ions to a polymer counterface, was studied. The presence of iron ions in the surface layer of styrene-butadiene rubber (SBR) vulcanizates and ebonite, rubbed against Armco iron was confirmed by ToF – SIMS, RBS and SEM – EDS analyses. It is commonly known that ions of multiple valence metals are destructive to rubber, facilitating the ageing of the material. An attempt was made to quantitatively analyse the process of the surface modification of polymer, determining working conditions and the durability of the rubber – metal friction pair.<br/><br/>

CHANGES IN THE MICROSTRUCTURE OF IRON BASED ALLOYS DURING TRIBOLOGICAL CONTACT WITH STEEL HEATED TO THE AUSTENITE RANGE
Hot forming of steel (including forging) is most often performed in the austenite region. Because of that, tribological properties of tools used in hot processing should be related to the conditions of their contact with...
ANALYSIS OF THE INFLUENCE OF BASIC CONSTRUCTIONAL PARAMETERS ON POWER LOSSES IN THE MESHING OF A TOOTHED CYLINDRICAL GEAR
Efficiency of gear depends, in significant measure, on power losses that occur in meshing, bearing and sealing. An amount of these losses depends on friction conditions in the named nodes of gear design, and it is define...
