摘 要：The galvanic corrosion behavior of carbon fiber reinforced polymers（CFRPs） GM-CFRP and Tepex-CFRP in contact with a Zn-coated DP590 steel in solution containing 0.9 wt%NaCl + 0.1 wt%CaCl2 + 0.075 wt%NaHCO3 was investigated.The results showed that the GM-CFRP/steel couple was initially more resistant to galvanic corrosion,but its galvanic corrosion activity gradually became higher than the Tepex-CFRP/steel couple.The different galvanic behaviors of these two couples were discussed based on the electrochemical performance of GM-CFRP,Tepex-CFRP and DP590 coupons in the testing solution.
