Abstract
This study subjected Inconel 690 alloy tubes to pre-immersion treatment in high-temperature and high-pressure (HTHP) artificial seawater (3.5 wt% NaCl) for different days (untreated, 1 day, 2 days, and 3 days). Then, impact-sliding fretting tribo-corrosion test rig was used to investigate its damage failure mechanism and electrochemical-corrosion dynamic response behaviors. Results showed that the oxidized corrosion layer that formed among the Inconel 690 alloy tubes surface increasingly densified with increased pre-immersion duration. These reduced the damage degree of fretting interface. However, the pre-formed oxidized corrosion layer accelerated the alloy tube’s electrochemical corrosion process. Additionally, the main impact-sliding fretting tribo-corrosion mechanisms of all test samples were abrasive wear, plastic deformation, and spalling.
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.
