The second approach is the less expensive and may have a high level of technological adaptation to the conditions of real machine-building production, and is capable of producing positive results on a large scale. First of all, these conclusions are related to favorable technological conditions for the sintering of single-phase nanoceramics from the relatively low cost of ZrO2 and Al2O3 or other ceramic nanopowders in comparison with the cost of the nanoscale modified electrically conductive phases (for example, graphene, graphene oxide). The other reason is the relatively low cost of materials for the production of a profile tool for EDM.
