Cemented carbides are a class of hard materials used extensively for cutting tools, as well as in other industrial applications. It consists of fine particles of carbide cemented into a composite by a binder metal. Cemented carbides commonly use tungsten carbide (WC), titanium carbide (TiC), or tantalum carbide (TaC) as the aggregate. Mentions of "carbide" or "tungsten carbide" in industrial contexts usually refer to these cemented composites. The cobalt content could vary from 5% to 23% base on application. 8% to 12% are the most common for cutting tools. Ruthenium is used to replace cobalt as a perfered binder for the best cutting performance.
CERAedge™ is a new coating introduced by MA Ford a while back that is starting to show some tremendous performance improvements when compared to amorphous diamond coatings. It combines the heat resistance of conventional AlTiN coating with the hardness and smoothness of amorphous diamond coatings.
