摘　　要：采用失重方法和电化学方法,研究碳钢/钛合金复合材料在3%NaC l溶液中的电偶腐蚀行为。结果表明,在碳钢/钛合金电偶腐蚀过程中,碳钢为阳极,钛合金为阴极,随着阴/阳面积比的增大,电偶电流增大,碳钢腐蚀速率变大,而电偶电位基本不变。The galvanic corrosion behavior of carbon steel/titanium alloy composite materials in 3% NaCl solution was studied using weight loss method and electrochemical process. The results show that the carbon steel is anode, titanium alloy is cathode in the processes of the galvanic corrosion of carbon steel/titanium alloy, the galvanic current and corrosion rate of carbon steel is increased with the increase of the area ratio of anode and cathode, and the galvanic potential does not basically change.
