Abstract
This study investigates the oxidative wear behaviors of Inconel 625 alloy in a simulated rotary calcination furnace environment at 600 and 800 ℃. Results show that both the coefficient of friction and wear loss increase with temperature from 600 °C to 800 °C. At 600 °C, the alloy exhibits strong resistance to oxidative wear, due to the formation of an intact oxide scale composed of Ni-Cr-O and Cr-rich layers. However, the oxide scale formed at 800 °C features a coarser grain structure, coupled with increased wear debris, leads to higher surface roughness and coefficient of friction. The oxide scale at 800 ℃ has poor effectiveness in protecting the substrate, being more prone to spallation and contributing to greater wear loss.
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.
