Abstract


  • Hot corrosion mechanism of Sodium Borate was investigated on mild-carbon steel at 800 °C by multiple surface

    characterizations. In addition, effects of tribological exposure on the interface chemistry were also examined in

    details by mean of ball-on-disk testing. The occurrence of interfacial reaction is characterized by the formation of

    a Sodium-rich film on the borate melt/oxide phase boundary. The basic dissolution reaction is accompanied by

    fluxing action of the protective scale in the case of static oxidation. External stressed shearing profoundly

    modifies the interface chemistry by establishing a hierarchical boundary film with remarkably low Oxygen

    density which renders improved oxidation resistance.
