Mechanism of lead-bronze corrosion by sulfur-containing fuels in the presence of water

  • Published:
Chemistry and Technology of Fuels and Oils Aims and scope

Conclusions

  1. 1.

    The deposits formed on the surface of VB-23NTs bronze parts in contact with moist fuel are from corrosion; the predominant metal in the deposits is lead (more than 30%), with copper not more than 2.5%.

  2. 2.

    Products from the oxidation of sulfur compounds present in fuel, e.g., sulfonic acids, are active corrosives in the presence of water. Aqueous solutions of benzenesulfonic acid are strong accelerators for the anodic dissolution of bronze.

  3. 3.

    When bronze is in contact with solutions of benzenesulfonic acid, both the anodic and the cathodic processes are reinforced.

  4. 4.

    The corrosion of lead bronze in contact with aqueous solutions of benzenesulfonic acid is selective in nature and is characterized by preferential transfer of the lead into solution.
