    Abstract
  • Galvanic corrosion between titanium alloy TC2 and two aluminum alloys (LY12,LC4) and two high-strength steels (30CrMnSiA,1Cr17Ni2) were investigated by galvanic corrosion testing,SEM and DES. The difference of galvanic corrosion behavior of two aluminum alloys and of galvanic corrosion behavior of two high-strength steels were analyzed. On the above basis,the rule of galvanic corrosion between titanium alloy and high-strength alloys was studied. By comparing the galvanic corrosion behavior of aluminum alloys with that of high-strength steels,the relationship between differential value of open circuit potentials and the value of galvanic corrosion current density was discussed. It was concluded that the galvanic couple of 1Cr17Ni2-TC2 can be available, but the galvanic couples of LY12-TC2,LC4-TC2 and 30CrMnSiA-TC2 should be avoided.
