· JVASP-21567· VCoB3

VCoB3 is a vanadium-cobalt boride intermetallic compound belonging to the hard ceramic-metal (cermet) family. It is an advanced research material being developed for ultra-high-hardness and wear-resistant applications where traditional cemented carbides reach performance limits. The material combines the hardness of boride ceramics with metallic toughness, making it of particular interest for cutting tools, abrasive applications, and extreme-wear environments, though industrial adoption remains limited as the material is still in development stages relative to established alternatives like tungsten carbide.
