摘要:
研究2-苯基咪唑(2-PhI)作为气相缓蚀剂在电路导电金属铜中的缓蚀性能，探讨其在不同腐蚀介质及温度条件下的缓蚀效果以及与有机胺复配后的性能提升情况。通过失重法和电化学法(极化曲线、交流阻抗谱)对2-PhI在盐酸、氯化钠和硫酸钠溶液中的缓蚀性能进行测试；改变2-PhI浓度(0、50、100、150、200和250 mg/L)、温度(25、40和55 ℃)及复配比例(2-PhI与三乙醇胺质量比为1﹕1、1﹕2和2﹕1等)，分析各因素对缓蚀性能的影响。随着2-PhI浓度增加，铜片腐蚀失重、腐蚀速率降低，缓蚀效率提升，250 mg/L浓度下在盐酸、氯化钠、硫酸钠介质中的缓释效率分别可达95.49%、86.46%和87.72%；不同介质中缓蚀性能为盐酸＞氯化钠＞硫酸钠；温度升高使腐蚀速率增加、缓蚀效率降低；2-PhI与三乙醇胺复配后缓蚀效果增强，1﹕2复配比例时在盐酸溶液中缓蚀效率达86.89%，且在不同温度下均展现更高缓蚀效率。2-PhI对铜具有显著的缓蚀作用，其缓蚀效果受浓度、介质类型和温度影响，与三乙醇胺复配可进一步提高缓蚀性能，有助于提升电路导电金属铜腐蚀防护的效果。
Abstract:
This paper investigates the corrosion inhibition performance of 2-phenylimidazole (2-PhI) as a gas-phase inhibitor in conductive metal copper. It explores its corrosion inhibition effect under different corrosive media and temperature conditions, as well as the performance improvement when combined with organic amines. The corrosion inhibition performance of 2-PhI in hydrochloric acid, sodium chloride and sodium sulfate solutions was tested by the weight loss method and electrochemical methods, such as polarization curve and alternating current impedance spectrum. The concentrations of 2-PhI (0, 50, 100, 150, 200, 250 mg/L), temperatures (25, 40, 55 ℃), and compound ratios (the mass ratios of 2-PhI to tritthanolamine were 1 ﹕1, 1﹕2, 2﹕1, etc.) were analyzed with the influence of each factor on the corrosion inhibition performance. With the increasing of 2-PhI concentration, the weight loss due to copper sheet corrosion, the corrosion rate decrease, and the corrosion inhibition efficiency increases. At a concentration of 250 mg/L, the slow-release efficiencies in hydrochloric acid, sodium chloride, and sodium sulfate media can reach 95.49%, 86.46%, and 87.72%, respectively. The corrosion inhibition performance in different media, such as hydrochloric acid is greater than sodium chloride, and which is in turn greater than sodium sulfate. The increasing of temperature leads to increasing of the corrosion rate and decreasing of the corrosion inhibition efficiency. The corrosion inhibition effect is enhanced when 2-PhI is compounded with triethanolamine. When compounded at a ratio of 1﹕2, the corrosion inhibition efficiency in hydrochloric acid solution reaches 86.89%, and it shows higher corrosion inhibition efficiency at different temperatures. 2-PhI has a significant corrosion inhibition effect on copper. Its corrosion inhibition effect is affected by concentration, medium type and temperature. When compounded with triethanolamine, the corrosion inhibition performance can be further improved, which is more helpful to enhance the corrosion protection effect of copper, a conductive metal in circuits
