摘要
为了抑制传统离子液体的金属腐蚀性,本文中合成了系列苯并三氮唑离子液体;研究了此类离子液体的物化性质、热稳定性和对钢的腐蚀性;在SRV摩擦磨损试验机上采用钢/钢摩擦副考察了室温和高温条件下此类离子液体的摩擦学性能;采用SEM和XPS对磨斑表面的进行了分析.结果显示:苯并三氮唑离子液体与含有相同阴离子的咪唑类离子液体相比,热稳定性略有下降,但在钢/钢摩擦副条件下其减磨抗磨性能占优,因此推断此类离子液体良好的抗磨性能归因于其对钢无腐蚀性.
In order to inhibit the serious corrosivity of conventional ionic liquids(ILs),a series of ILs containing benzotriazolium cations were synthesized. The physicochemical properties, thermal stabilities of these synthesized benzotriazolium ILs and the corrosion to steel were studied. The tribological properties of the synthesized ILs as lubricants for a Steel-Steel System were evaluated on an SRV friction and wear tester at room temperature and 150 ℃. The worn surfaces were analyzed by scanning electron microscopy and X-ray photoelectron spectroscopy. It is found that,the benzotriazolium ILs possessed lower thermal stability but better friction-reducing and anti-wear ability than conventional imidazolium IL,which had the same anion as the benzotriazolium one. And more importantly,these benzotriazolium ILs had no corrosivity to steel,which was one of the important reasons for their better anti-wear ability.
