Abstract
The tribological behavior of tungsten inert gas (TIG) welded high entropy alloy (HEA) FeNiCrCoMo cladding deposited on AISI 1050 steel substrate was studied. The response surface methodology (RSM) optimized the TIG welding parameters. The SEM images revealed no signs of intermetallic compounds in the cladding, and the XRD analysis showed that the FeNiCrCoMo greatest peak corresponds to the BCC+FCC mixed phase. The microhardness and sliding wear resistance of the cladding were superior compared to the steel substrate owing to the solid solution strengthening and the presence of mixed phase. The worn surfaces of HEA claddings showed the presence of wear debris, grooves and micro-cutting from sliding wear as revealed by the SEM and 3-D profilometry images.
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.
