摘要

将 Inconel 601 超级合金样品表面在 1000 ℃ 下进行 4 小时和 6 小时的包硼处理，以研究硼化处理对机械性能和高温磨损性能的影响。使用扫描电镜、EDS、XRD、显微硬度测试、纳米压痕以及室温和 500 ℃、7 N 和 15 N 正常载荷下的高温磨损测试对硼化物层进行了表征。硼化使 Inconel 601 表面的硬度提高了近 300%，磨损性能提高了 11 倍。尽管 COF 和特定磨损率较低，但与未经处理的 Inconel 601 表面相比，硼化表面更容易受到温度升高的影响，原因是含有硬质相的磨损碎片更不容易形成稳定的润滑层。

Tribological response of pack-boronized inconel 601 superalloy surfaces at elevated temperatures

Inconel 601 superalloy sample surfaces were pack-borided at 1000 °C for 4 h and 6 h to investigate the effect of boriding treatment on the mechanical and high temperature wear performance. The boride layers were characterized using SEM, EDS, XRD, microhardness tests, nanoindentation and high-temperature wear tests at room temperature and 500 ℃ under 7 N and 15 N normal loads. Boriding led to nearly 300 % increase in the hardness and up to 11-fold increase in the wear performance of the Inconel 601 surfaces. Despite lower COF and specific wear rates, borided surfaces were more susceptible to temperature increase than the non-treated Inconel 601 surfaces due to the lower tendency of wear debris with hard phase content to form a consistent lubricating layer.

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.
