MODIFICATIONS OF SHS PROCESSES

Proceeding from the kind of the chemical bond, the majority of the processing versions of the self- propagating high-temperature synthesis (SHS) of the refractory inorganic compounds can be divided into two groups: element and oxide. By performing the chemical transformation in the combustion mode and employing the high exothermic nature of the initial systems, processing techniques and special equipment, it is possible to tackle the various practical problems and obtain the SHS spectrum of the products, namely; powders and compacts (TiC SiC, Cr3C2, TaC, B4C, TiB2, CrB2, MoSi2, TiSi2, V3Si, TiN, BN,AIN, Si3N4, YBa2Cu3O7-x and others), high-dense items manufactured from the above-listed materials (rollers,pipes, milling cutters, cutters, electrodes, bushings, rings etc.) and the items with the preset porosity (filters), as well as to weld the refractory materials (graphite with graphite, steel with carbide alloys, molybdenum with molybdenum and so on) and to obtain the protective coatings of various thickness.
