Value of the ion energy and the ion charge states greatly affect the grain size (with increasing energy of the charge and the grain size increases). Increase the percentage composition of the tungsten carbide results in grain growth, and with the increasing mass ion reduction of the grain size is more significant that it can be used to obtain the required grain size. Designing a cutting tool material with the possibility of for-mation of nanostructures shows that not always increase the proportion of tungsten carbide tool enhances the performance and efficiency, and often the grain size has a decisive influence.
