Tribological performance of fatty acid modification of sol–gel TiO2 coating

Improving wear resistance of aluminum by hydrophobic sol-gel-derived TiO2 film

“…The oxide underlayer can not only increase wear resistance of the substrate but also provide surface hydroxyl groups for strong bond of organic film. In the past, we have found that fatty acids modified sol-gel-derived TiO 2 film on the glass and steel substrates shows significantly reduced friction and wear in an unlubricated sliding with a steel ball (Wan et al, 2012;Dong et al, 2013). So, in this paper, we continue our efforts to improve the wear performance of aluminum by using chemically modified TiO 2 film.…”

“…The TiO 2 film on the aluminum substrate was prepared by solgel method using tetrabutyl titanate as a precursor material and triethanolamine as a stabilizing agent in anhydrous ethanol (Wan et al, 2012). First, tetrabutyl titanate was added to an anhydrous ethanol solution.…”

SINTESIS PERMUKAAN KACA HIDROFOBIK MELALUI KOMBINASI TiO2/ASAM STEARAT UNTUK APLIKASI MATERIAL SELF-CLEANING

“…Pada kaca terlapis asam stearat juga terlihat adanya vibrasi regangan pada 3409 cm -1 yang merupakan bilangan gelombang spesifik dari OH yang merupakan gugus kepala asam stearat. (Wan, Sun, Liu, & Qi, 2012) (Liao et al, 2018).…”

Graphite and Hybrid Nanomaterials as Lubricant Additives

“…Other capping agents used to functionalize the surface of nanoparticles include stearic acid and oleic acid, which can increase the tribological properties substantially in comparison to the bare nanoparticles in oil, according to the studies performed by different groups [19,30,[87][88][89]. Xu et al prepared surface-coated copper nanoparticles with FCC structure, and characterized their tribological properties using ball-on-disc tester and ring-on-block tester [90].…”
