摘要：

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.
