Abstract

CFRP precision grinding is a critical process in aeronautical industry. To enhance surface integrity, ultrasonic-assisted MQL grinding with nanolubricants was developed. The effects of ultrasonic on permeation mechanism and fluid dynamic pressure lubrication were investigated. The mechanical behavior of droplet anisotropic spreading, contact line dynamics, and capillary action was analyzed. Additionally, tribological properties of CFRP grinding surfaces with various fiber orientation angles were evaluated. The findings reveal contact angles in vertical grinding direction are higher than those in parallel direction. The application of 2D ultrasonic vibration decreased stable aspect ratio and increased spreading speed of droplets. Nanolubricants demonstrated significant improvements in reducing friction coefficient, grinding force ratio, wear area and volume, with a maximum reduction in friction coefficient of 34.87 %.

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.
