In this article the way of forecasting of quality indicators (fracture toughness, hardness) ofelectroconsolidated materials of ZrO2 - Al2O3 nanosystem is considered by a method of mathematicalmodeling.The main patterns of influence of technological factors eleсtroсonsolidation and concentration ofinitial components for the synthesis of materials using zirconia and alumina nanopowders on the strengthcharacteristics of the materials were identified. The mathematical models were built. The model is easy toassess the extent and impact of the results of each of the factors (temperature, holding time and Al2O3concentration) on the characteristics of the object, find it optimal regimes operation. The active experimentallows putting the artificial indignation on object under study and measuring the corresponding valuesoutput parameters. The size and mix of revolting influences introduced into the facility in accordance with adefinite plan, for any optimal criteria.
