摘要：
A literature review on the corrosion resistance of Ph and Pb alloy anodes used in hydrometallurgy is presented. Data from many authors show that Ph alloys that contain Ag, Co or Tl are the most resistant. The increased corrosion resistance of these anodes is explained by the decreased current density and the decreased potential of the lead component of the alloy due to the higher conductivity of the alloying metals as compared with that of lead. As a result, a greater part of the current is distributed on the alloying metal in spite of its high positive potential. (C) 2000 Elsevier Science B.V. All rights reserved.
