Abstract
Nanodiamond/Mo reinforced in-situ synthesized NiAl-based composite coatings were prepared by laser cladding. The microstructure, microhardness, and tribological properties of these composite coatings were studied. The results show that the coating is mainly composed of NiAl and Ni3Al phases. ND and Mo show a synergistic effect, which not only reduces the porosity of the coating, refines the grain size, and also improves the microhardness. In addition, in the temperature range of 25–800 °C, they reduce the friction coefficient and wear rate of the coating. These findings provide a valuable reference for optimizing the performance of NiAl-based composite 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.
