Obtaining ceramic and composite materials using a combination of methods of self-propagating high-temperature synthesis and electric spark sintering (review)

The review is devoted to the possibilities of combining self-propagating high-temperature synthesis (SHS) and electrospark sintering (EIS) for obtaining monophase ceramic materials and composite materials with ceramic and metal matrices. The materials covered in this review contain compounds formed in the SHS mode: carbides, borides, metal silicides, and intermetallides. Factors in the structure formation of materials obtained by sintering of SHS products and the influence of EIS conditions on the characteristics of the materials (relative density, grain size) are analyzed. Advantages of combining SHS and EIS methods, including the possibility of additional processing of the SHS product (grinding, adding components) to modify the composition of the material and its properties, are discussed.
