Special Issue Information
Dear Colleagues,
The limited natural resources and severe environmental issues that humanity is currently facing inherently drive the need for sustainable development in nearly every industry, such as aerospace, marine, automobile engineering, and manufacturing. To eliminate the negative effect of traditional mineral lubricants, the use of biolubricants is widely researched in the tribology and manufacturing fields. Its improved anti-wear and anti-friction performance have been preliminarily verified by experimental studies. Previous studies have also concluded the major influencing factors of tribological properties, including nano-enhancement, molecular structures, physicochemical properties, and so on. Nevertheless, the complex action of biolubricants is indistinct, which limits the preparation of process specifications and their popularity in factories.
The current Special Issue concentrates on the comprehensive assessment of tribological biolubricants based on innovative preparation methods, improved tribological testing, and in-depth mechanism analyses. Then, it attempts to present new perspectives for engineering applications of biolubricants based on the following aspects: (i) the development of raw materials for the preparation of biolubricants, (ii) improvement strategies for lubrication performance from a molecular point of view, (iii) the exploration of green and high-performance additives, (iv) and application guidance for different working conditions, especially extreme conditions such as high temperatures or low temperatures. Contributions are welcome from all scientists working in tribological, chemical, and related areas.

Electrostatic atomization minimum quantity lubrication (EMQL) technology has been developed to address the need for environmentally friendly, efficient, and low-damage grinding of challenging titanium alloy materials. EMQL leverages multiple physical fields to achieve precise atomization of micro-lubricants, enabling effective lubrication in high temperature, high pressure, and high-speed grinding environments through the use of electric traction. Notably, the applied electric field not only enhances atomization and lubrication capabilities of micro-lubricants but also significantly impacts heat transfer within the grinding zone. In order to explore the influence mechanism of external electric field on spatial heat transfer, this paper first comparatively analyzes the grinding heat under dry grinding, MQL, and EMQL conditions and explores the intensity of the effect of external electric field on the heat transfer behavior in the grinding zone. Furthermore, the COMSOL numerical calculation platform was used to establish an electric field-enhanced (EHD) heat transfer model, clarifying charged particles’ migration rules between poles. By considering the electroviscous effect, the study reveals the evolution of heat transfer structures in the presence of an electric field and its impact on heat transfer mechanisms. Full article
