It was found that the use of zirconia as matrix material does improve the toughness and strength compared to alumina based composites whereas the drawback of zirconia based materials concerning machinability and lower hardness can be only partially compensated by adjusting the titanium carbide content.
Electrical discharge machining (EDM) is an established process for machining of materials with high hardness such as hardened steel or cemented carbides for mold design and construction.
