The possibility to create materials for use as a matrix of sintered composite diamond-containing materials (CDMs) is shown. The results of experimental studies on the dependence of the structure of 26Fe–25Cr–32Cu–9Ni–8Sn CDM matrices manufactured by spark plasma sintering on the ZrO2 additive content (ranged from 0 to 10%) are presented. The development of metal matric composites based on Fe–Cr–Cu–Ni–Sn matrices with ZrO2 additives is a new approach to replacing the basic materials, which are commonly used in tools for stone processing industry. In the initial state, a 26Fe–25Cr–32Cu–9Ni–8Sn composite sample has a nonuniform distribution of elements. It is shown that the addition of ZrO2 micropowder to the 26Fe–25Cr–32Cu–9Ni–8Sn composite makes it possible to form a structure, whose parameters can be purposefully controlled by changing its concentration. Under such conditions, the composites containing the ZrO2 additive have a more uniform distribution of elements. Stable correlations have been established between the ZrO2 additive content and the microstructure parameters.
