Novel water-based nanolubricants using TiO₂ nanoparticles (NPs) were synthesised by adding sodium dodecyl benzene sulfonate (SDBS) and glycerol, which exhibited excellent dispersion stability and wettability. The tribological performance of the synthesised nanolubricants was investigated using an Rtec ball-on-disk tribometer, and their application in hot steel rolling was evaluated on a 2-high Hille 100 experimental rolling mill, in comparison to those without SDBS. The water-based nanolubricant containing 4 wt% TiO₂ and 0.4 wt% SDBS demonstrated superior tribological performance by decreasing coefficient of friction and ball wear up to 70.5% and 84.3%, respectively, compared to those of pure water. In addition to the lubrication effect, the suspensions also had significant effect on polishing of the work roll surface. The resultant surface improvement thus enabled the decrease in rolling force up to 8.3% under a workpiece reduction of 30% at a rolling temperature of 850 C. The lubrication mechanisms were primarily ascribed to the formation of lubricating film and ball-bearing effect of the TiO₂ NPs.

通过添加十二烷基苯磺酸钠（SDBS）和甘油，合成了使用TiO ₂纳米颗粒（NPs）的新型水基纳米润滑剂，其分散稳定性和润湿性极好。使用Rtec圆盘摩擦计对合成的纳米润滑剂的摩擦学性能进行了研究，并与没有SDBS的相比，在2高Hille 100实验轧机上评估了它们在热轧钢中的应用。包含4 wt％TiO ₂的水基纳米润滑剂和纯净水相比，SDBS和0.4wt％的SDBS的摩擦系数和球磨损分别降低了70.5％和84.3％，从而显示出优异的摩擦学性能。除润滑作用外，悬浮液还对工作辊表面的抛光产生重大影响。因此，在850℃的轧制温度下，在工件减少30％的情况下，所得的表面改善性能使轧制力降低了8.3％。润滑机理主要归因于TiO 2的润滑膜的形成和滚珠轴承的作用。_2个NP。
