Abstract
To investigate the loosening failure mechanism of bolted joint structures in aero-engines caused by fretting damage, an experimental investigation was conducted to analyze the fretting wear behavior and failure mechanisms of GH2132 superalloy under varying temperature conditions in the present study. The results revealed a significant reduction in the wear rates of the specimen at 600°C compared to both room temperature and 300°C. Compared with room temperature, the wear rates of the specimen at 600°C decreased by 39.38 µm3/mJ in the mixed regime and 43.89 µm3/mJ in the slip regime. The formation of a dense and intact third-body layer was identified as a key factor in mitigating fretting wear damage.
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.
