“…The crystal cells in the crystal structure are composed of two layers of silica tetrahedra with an aluminum oxide octahedron in the middle. This unique two-dimensional layered nanostructure can effectively reduce friction and wear during drilling operations. , The high cation exchange properties of montmorillonite allow to modify it and expand its application fields . Therefore, various intercalators are used to modify MMT materials in order to obtain a large layer spacing and diverse functions.…”

In this study, a water-soluble quaternary ammonium salt (QAS)-functionalized montmorillonite (MMT) was fabricated using a mechanochemical method as a high-performance water lubrication additive. The intercalation of QAS into the MMT layer expands the layer spacing of MMT, but does not affect the hydrophilicity of MMT. The ultrathin layer QAS-functionalized montmorillonite (QAS-MMT) demonstrated excellent water-stable dispersion and can be used as a water-based lubrication additive. Only 0.1% addition can reduce the friction coefficient by more than 71.4% and the wear volume by about 58.8% when compared to water, demonstrating its excellent friction reduction and antiwear performance. The frictional mechanism indicates that the physical adsorption film, together with the chemical reaction film, endows the QAS-MMT additives with outstanding tribological performance, provides excellent lubrication for the contact of steel/steel pairs, and prevents the steel surface from being further worn.

“…As an example, Trzepieci ński [13] compared different lubricants based on a combination of boric acid (H 3 BO 3 ) and edible vegetable oils (both of which are natural and environmentally friendly) with traditional petroleum-based lubricants; it was found that palm oil as pure oil or with the addition of 5 wt.% of H 3 BO 3 , was the most effective in reducing the CoF. Ortega et al [14] investigated the lubrication performance of corn and peanut oils reinforced with different concentrations of Halloysite clay nanotubes (HNTs) and Montmorillonite nanoclay (MMT) as green lubricant additives. Block-on-ring wear tests were conducted to investigate the effect of different nanoparticle (NP) concentrations on the Coefficient of Friction (COF) and wear volume loss.…”

Lubrication in the cold rolling process plays a key role in withstanding the loads between the strip and the work rolls, as well as in ensuring high surface quality, tight geometric tolerances, and large thickness reductions. Most of the currently used lubricants have synthetic or semi-synthetic formulations, but the research for greener alternatives, able to guarantee very low environmental impact during both the preparation (use of natural raw components) and the disposal, is increasingly playing a key role. In the present work, the lubricating performance of a natural-based emulsion and a mineral-based one has been assessed in terms of rolling forces, Coefficient of Friction (CoF) at the roll/strip interface, and work rolls’ wear. Data from the two-stands reversing cold mill (RCM) at the Marcegaglia plant (Ravenna, Italy) were used for comparing the investigated lubricants. In particular, data about the forces and the wear evolution during the rolling process were acquired over quite a long period (11 months), thus being related to a large type of steel. In addition, the CoF was evaluated using the CSM High-Temperature pin-on-disk Tribometer (THT) and replicating the operating conditions in which the two lubricants are currently used. Laboratory tests revealed that the green lubricant is characterized by a better lubricating performance (the CoF value of the green lubricant is about 10% lower than the one of the semi-synthetic formulation). Such a result was confirmed by both the rolling forces (an average reduction equal to 5.6% was obtained by using the green lubricant) and by the work rolls’ wear (less frequent maintenance of the rolls), thus determining a large and valuable reduction of the process-related costs.
