“…The common practice to such improvement is by adding or appending particles that possess a desirable properties that can potentially improve the base lubricant, some researchers have recognized the micro-scale properties of the additives for base lubricant, with specific interest on the thin film lubrication, they enhanced the blend mixture additive with an approach built by developing relationship among the additive important properties such as density, viscosity and volume fraction [1]. Nowadays, most of the modern lubricants consist of polymeric additives that can influence the base lubricants to slight shear thinning and mostly viscoelastic [2].…”

Abstract. In this paper, the effects of additives on the base lubricants has been investigated and reported, aiming for enhancement and the improvement of hydrodynamic journal bearing performance. A pair of additives volume fractions with a viscosity ratio were considered as blended with the base binder. A dimensionless pressure distribution with improved viscosity over the lubricant film has been identified. The results show an increase on the pressure distribution in response to increase in volume fraction of the additives.

“…The method to calculate the temperature of the lubricant during friction was based on the temperature of the housing, the temperature of the environment, the velocity, and the mechanical system to predict slow changes in friction parameters. The reduction of heat transmittance using lubricants was investigated in the work by Zohdi [19]: The research aimed to design microscopic additives that allow for a smaller heat dissipation during sliding.…”

Sustainability has become of paramount importance, as evidenced by the increasing number of norms and regulations concerning various sectors. Due to its intrinsic trans-sectorial nature, tribology has drawn the attention of the supporters of sustainability. This discipline allows the environmental, economic, and social impacts to be decreased in a wide range of applications following the same strategies. In 2010, Nosonovsky and Bhushan drew up 12 approaches based on the 12 principles of green chemistry and the 12 principles of green engineering, defining the “12 principles of green tribology.” This review exploits the 12 principles of green tribology to fathom the developed research related to sustainability and tribology. Different approaches and innovative studies have been proposed in this short selection as references to consider for further development, pursuing the efforts of the scientific community for a sustainable future through the contribution also of tribosystems. The manuscript aims to provide practical examples of materials, lubricants, strategies, and technologies that have contributed to the overall progress of tribology, decreasing wear and friction and increasing efficiency, and at the same time promoting sustainable development, lowering toxicity, waste production, and loss of energy and resources.
