Tribological Behavior of Plant Oil-Based Extreme Pressure Lubricant Additive in Water-Ethylene Glycol Liquid

“…The reason may explain as follows: Firstly, the long alkyl chains absorb on the stainless steel surface and form physical boundary lubrication film. Secondly, during the friction under high pressure, the active phosphorus in the RSOPE can react with metal and generate tribochemical reaction film [23][24][25]. Fig.…”

Performance Evaluation and Lubrication Mechanism of Water-Based Nanolubricants Containing Nano-TiO2 in Hot Steel Rolling

“…Therefore, when the concentration of nano-TiO 2 is lower than 4.0 wt%, there are insufficient TiO 2 NPs left to form lubricating film and make rolling effect due to loss of nanolubricants when contacting the hot steel surface. When the concentration of nano-TiO 2 exceeds 4.0 wt% to a higher level of 8.0 wt%, instead, the rolling force varies at an opposite trend to present a higher value (see Figure 2) because of the agglomeration of TiO 2 NPs [20,21], which aggravates the friction between the work roll and the workpiece.…”

“…In this regard, a type of environment-friendly lubricant with excellent lubricating performance is urgently needed to substitute conventional oil-containing lubricants. In recent years, the research trend on water-based lubricants added with nanoparticles (NPs) is continuously ascending due to their excellent tribological properties and promising potential in hot steel rolling, even though the relevant reports are still scarce [8,[16][17][18][19][20][21][22][23]. For instance, Bao et al [8] carried out hot steel rolling tests at temperatures of 750-950 • C using water-based lubricants containing SiO 2 NPs, and found that the use of as-prepared lubricants with the addition of 0.5 wt% nano-SiO 2 resulted in improved surface morphology, reduced oxide scale thickness, and refined grain size, compared to that of the base lubricant.…”

An investigation on the tribological behaviors of steel/copper and steel/steel friction pairs via lubrication with a graphene additive

“…Steel/steel and steel/copper friction pairs are typical moving parts in machines such as bearings and hydraulic pumps. Several studies have been conducted on friction and wear in steel/copper [1][2][3][4][5][6] and steel/steel [7,8] friction pairs under lubricated or dry friction conditions. In general, steel has relatively low wear during friction owing to its high hardness according to the Archard wear equation [9].…”
