摘要

本研究利用激光熔覆（LC）技术研究了 AISI 52100 轴承钢上铁铬钼碳非晶涂层的机械和摩擦学特性。将两种具有不同 LC 参数的样品与未涂层的抛光钢进行了比较。分析方法包括扫描电子显微镜 (SEM)、X 射线衍射 (XRD)、显微硬度测试以及在干燥和润滑条件下通过高频往复式摩擦仪 (HFRR) 进行的摩擦学测试。在干燥条件下，样品 S1 的显微硬度是未涂层钢的五倍，磨损体积损失减少了 95%。在油脂润滑条件下，S1 的摩擦系数降低了 20%，磨损体积损失降低了 93%。样品 S2 的性能也优于未涂层的钢材。这些结果凸显了铁铬钼碳化物涂层的显著优势。

Investigation of the tribological and mechanical properties of FeCrMoCB coating on AISI 52100 bearing steel

This study examines the mechanical and tribological properties of FeCrMoCB amorphous coatings on AISI 52100 bearing steel using laser cladding (LC). Two samples with varying LC parameters were compared to uncoated polished steel. Analytical methods included scanning electron microscopy (SEM), X-ray diffraction (XRD), microhardness testing and tribological tests via a high-frequency reciprocating rig (HFRR) tribometer under both dry and lubricated conditions, were employed. Sample S1 exhibited a microhardness five times that of uncoated steel and a 95 % reduction in wear volume loss under dry conditions. Under grease-lubricated, S1 showed a 20 % reduction in the coefficient of friction and a 93 % reduction in wear volume loss. Sample S2 also outperformed uncoated steel. These results highlight the significant benefits of FeCrMoCB coatings.

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.
