  • Chemical aspects of wear of alumina ceramics
    Novak, Saša ; Kalin, Mitjan ; Kosmač, Tomaž, 1948-2022
    In our investigation, the effects of tribochemically-induced dissolution of alumina ceramics and modulation of near-surface forces (surface charge) within the tribo-contact were studied. The wear and ... friction behaviors of alumina were investigated using a reciprocating sliding test in different chemical environments. The samples for the tests were hemispherical pins and plates of polished alumina, both prepared by near-net-shaping method. The sliding tests were conducted in water-based liquids with different pH values or with addition of a polyelectrolyte to control the surface charge at solid surfaces. The coefficient of friction was continuously recorded during the test and the wear loss was subsequently determined for all samples. The results show a significant effect of the chemical agents on the coefficient of friction as well as on the material removal rate in different aqueous media. The results are discussed in terms of the chemical and electrochemical properties of the materials in the tribo-contact.
