In the relentless pursuit of enhancing industrial efficiency and longevity, researchers have turned to the nanoscale to unlock new possibilities. A recent study led by Evgeny V. Fominov from Don State Technical University in Rostov-on-Don, Russia, has shed light on the potential of nanodiamonds produced through cavitational synthesis to revolutionize cooling lubricants in the energy sector. Published in the journal *Frontiers in Materials and Technologies* (translated from Russian), the research delves into the tribological properties of water-oil-based cooling lubricants, offering promising insights for commercial applications.
The study focuses on the influence of nanosized diamonds on the tribological properties of a commercial water-oil-based cooling lubricant. Tribological tests were conducted using a high-speed P18 steel indenter and a 30HGSA steel disk, simulating real-world friction conditions. The researchers explored two variants of the base lubricant modified with colloidal dispersions of nanodiamonds, with final additive concentrations of 0.5% and 2.5%.
The results were striking. Both modifications significantly increased the bearing capacity of the lubricating layers and reduced the total linear wear of friction couple elements by 1.8 to 2.4 times. The presence of nanodiamonds also enhanced the shielding effect of the cutting coolant, leading to a decrease in visible damage to friction surfaces. Optical microscopy revealed a reduction in the size of grooves on the counterbody and a decrease in surface roughness from Ra=0.49 μm to Ra=0.29–0.34 μm.
“These findings suggest that the use of cavitational synthesis nanodiamonds as an additive could be a game-changer for the energy sector,” said Fominov. “The enhanced antiwear properties and reduced friction could lead to more efficient and durable machinery, ultimately lowering maintenance costs and improving overall performance.”
The study’s implications are far-reaching. In an industry where even minor improvements in lubrication can translate to significant cost savings and environmental benefits, the potential of nanodiamonds is substantial. The research indicates that the use of nanodiamonds as an additive may become a promising direction for increasing the antiwear properties of water-oil-based cooling lubricants, paving the way for more advanced and efficient industrial applications.
As the energy sector continues to evolve, innovations like these are crucial. The integration of nanodiamonds into cooling lubricants could not only enhance the performance of existing machinery but also drive the development of new technologies. The study’s findings, published in *Frontiers in Materials and Technologies*, offer a glimpse into a future where nanotechnology plays a pivotal role in shaping the energy landscape.
In the words of Fominov, “This research opens up new avenues for exploration and application. The potential is immense, and we are excited to see how these findings will influence the industry moving forward.”
