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.

本研究探讨了 Inconel 625 合金在 600 ℃ 和 800 ℃ 模拟旋转煅烧炉环境中的氧化磨损行为。结果表明，从 600 ℃ 到 800 ℃，摩擦系数和磨损损耗均随温度升高而增加。在 600 ℃ 时，由于形成了由 Ni-Cr-O 和富铬层组成的完整氧化鳞，合金表现出很强的抗氧化磨损性。然而，在 800 ℃ 时形成的氧化鳞具有更粗的晶粒结构，再加上磨损碎片的增加，导致表面粗糙度和摩擦系数升高。800 ℃ 时的氧化鳞片对基体的保护效果较差，更容易剥落，造成更大的磨损。

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.
