摘　　要：通过扫描电子显微镜、接触角和电化学工作站等测试方法,研究了γ-氨丙基三甲氧基硅烷(γ-APS)自组装膜对铜合金表面在3.5%NaCl溶液中的耐腐蚀性。结果表明,经酸性FeCl 3溶液刻蚀,再在V(γ-APS)∶V(乙醇)∶V(水)=1∶9∶20、温度30℃、水解8 h的γ-APS溶液中自组装50 min,构建的铜合金表面硅烷膜接触角可从处理前的73°增大到119°,此时表面硅烷膜在模拟海水的实验中对铜合金的缓蚀效率可达89.2%。The corrosion resistance ofγ-aminopropyltrimethoxysilane(γ-APS)self-assembled film on the surface of copper alloy in 3.5%NaCl solution was studied by scanning electron microscopy,contact angle and electrochemical workstation.The results show that self-assembly inγ-APS solution after etching with acidic FeCl 3 solution and V(γ-APS)∶V(ethanol)∶V(water)is 1∶9∶20,temperature 30℃,hydrolysis for 8 hours.costs 50 minutes,and the contact angle of the silane film on the surface of the copper alloy was increased from 73°to 119°before the treatment.At this time,the corrosion inhibition efficiency of the surface silane film on the copper alloy was 89.2%.
