Abstract

In this study, the tribological behavior of Ti-6Al-4V is investigated by the cooling properties (thermal conductivity, volume specific heat), lubrication properties (oil film thickness, surface morphology, friction coefficient), and wetting properties (contact angle) of the emulsion. The results show that the developed emulsions exhibit excellent lubrication and cooling properties. Compared to dry grinding and oil lubrication, the friction coefficients of the emulsion lubrication decreased by 59.3 % and 45.51 %, respectively, and the temperature in the contact area decreased by 32.29 % and 17.58 %, respectively. Additionally, the adhesive wear and abrasive wear in the contact area are reduced under emulsion lubrication conditions, which mitigates the wear of Ti-6Al-4V and WC-6Co. This study provides important guidance for the efficient grinding of Ti-6Al-4V.

本研究通过乳液的冷却性能（热导率、体积比热）、润滑性能（油膜厚度、表面形态、摩擦系数）和润湿性能（接触角）对 Ti-6Al-4V 的摩擦学行为进行了研究。结果表明，所开发的乳液具有出色的润滑和冷却性能。与干磨和油润滑相比，乳液润滑的摩擦系数分别降低了 59.3 % 和 45.51 %，接触区域的温度分别降低了 32.29 % 和 17.58 %。此外，在乳化液润滑条件下，接触区的粘着磨损和磨料磨损也有所减少，从而减轻了 Ti-6Al-4V 和 WC-6Co 的磨损。这项研究为 Ti-6Al-4V 的高效磨削提供了重要指导。

期刊介绍： Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International. Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
