Vegetable oil-in-water emulsions are common cold rolling lubricants. However, maintaining the required dispersion for polar oil droplets for consistent lubrication and proper surface self-cleaning after rolling remains a practical challenge. In this study, titanium silicate TiO2-SiO2 nanoparticle (NP)-stabilized soybean oil emulsions are produced and NPs functions as dispersant, lubrication enhancer, and detergent agent to clean up oil residue are explored. Cold rolling of SS316 strips reveals a threshold of NPs wt%, at which stably dispersed oil droplets improve tribology and lower the rolling parameters relative to without or at high wt% of NPs. Cleaner as-rolled strips are also obtained with NPs. Favorable results are attributed to the formation of NP-coating layers on oil droplets which enhances dispersion, optimizes plate-out while keeping adequate wetting, and provides a three-body abrasive rolling as opposed to two-body adhesion without NPs.

Nanofluids are known for their heat transfer abilities. Despite their potential for industrial applications, their instability is a bottleneck for practical implementation.
Applying nanomaterials and nanotechnology in lubrication has become increasingly popular and important to further reduce the friction and wear in engineering applications. To achieve green manufacturing and its sustainable development, water-based nanolubricants are emerging as promising alternatives to the traditional oil-containing lubricants that inevitably pose environmental issues when burnt and discharged. This review presents an overview of recent advances in water-based nanolubricants, starting from the preparation of the lubricants using different types of nanoadditives, followed by the techniques to evaluate and enhance their dispersion stability, and the commonly used tribo-testing methods. The lubrication mechanisms and models are discussed with special attention given to the roles of the nanoadditives. Finally, the applications of water-based nanolubricants in metal rolling are summarised, and the outlook for future research directions is proposed.
