Abstract
AlCoCrFeNiTiWC high-entropy alloy (HEA) coatings were prepared using laser cladding technology with continuous laser and air cooling, as well as pulsed laser with water cooling. The phase structures of the coatings were BCC, (Ti,W)C, and μ phase. The carbides and μ phase in the pulsed laser with water-cooled coating were refined, and the proportion of the μ phase decreased. The wear resistance of the pulsed laser with water-cooled coating significantly increased, which can be attributed to the reduction in the proportion of μ phase, the refinement of carbides, and the formation of a wear lubrication layer. The pulsed laser with water cooling enhanced the thickness and uniformity of the passivation film on the coating surface, thereby improving corrosion resistance.
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.
