| Popis: | Refinement of lamellar spacing down to a few nano-meters in pearlitic steels offers a unique combination of high strength and toughness. The present work pertains to the tribological response of nano-structured pearlitic steels with varying lamellae spacing under repeated frictional sliding using a conical diamond tip. The wear response has been quantified through the friction, volume of groove formed by the indenter and deformation-induced structural changes with number of passes of sliding. Results indicate that the initial microstructure and mechanical properties have a profound impact on the wear resistance since these factors also govern the microstructural adaptability under repeated sliding. The finest lamellar spacing pearlite shows the least wear volume, lowest friction coefficient and the smallest deformation-affected zone. [GRAPHICS] . |
