Acoustic emission analysis of seizure transition process between steel journals and aluminum alloy plain bearings
Seizure tests were conducted using a bearing tester to elucidate the mechanism of seizure occurring between aluminum alloy (Al-Sn-Si) plain bearings widely used in gasoline engines and steel journals. Differences in torque spikes that occurred before seizure and final seizure were determined by analyzing the sliding surfaces and cross sections and the acoustic emission signal. The results revealed that the occurrence of final seizure was affected by the melting out and depletion of tin in the bearing alloy, plastic deformation due to frictional heat, and expansion of the aluminum adhesion zone caused by these factors.
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.
