Abstract
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.
