Abstract
A few super wear-resistant materials can maintain stable performance in moist environment where WB4-B material as a new superhard material shows a potential for wear resistance. We investigated the wear compatibility of super-hard WB4-B material coupling with steel, Si3N4, Al2O3, and SiC materials, suggesting that WB4-B material against with SiC ceramic exhibits the super wear-resistant and self-lubricating properties with a wear rate to 2.31 × 10−8 mm3N−1m−1 and a friction coefficient to 0.1. The ultra-low wear mechanism is that the combined lubrication film of H3BO3/WO3·H2O/SiO2·H2O synergizes with the superhard properties of WB4-B. These findings provide a reference to the design and development of super wear-resistant materials.
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.
