coatings, and to obtain porous functional materials in long-term microgravity. Also, study the
effect of long-term weightlessness on the interaction between melted self-propagating, high-
temperature synthesis products and metal bases.
SVS-6
Study the mechanism of combustion and formation of macro and microstructures in condensed
reaction products, the structure of pore volumes, and transitional areas at joints (welds) in
samples with varying porosity and chemical composition, the
mechanism and kinetics of the formation of intermetallics
and high-melting inorganic compounds at the borders of
metals with self-propagating, high-temperature synthesis
system components. Completing these tasks will make it
possible to develop technologies for the formation of
materials and compounds with given properties necessary
for further space exploration.
SPACE BENEFITS
Establishing the mechanism of combustion and structural
formation in self-propagating, high-temperature synthesis
systems in weightlessness will make it possible to obtain
high-melting materials with unique foam structures or
granular frameworks, which are efficient heat insulating
materials for use in space technology. Investigating the
materials obtained through self-propagating, high-
temperature synthesis in long-term microgravity
demonstrated the potential for obtaining highly porous foam
materials and coatings for use in the aerospace industry in
weightlessness.
RESULTS
In the framework of the experiments conducted, the
mechanisms of combustion and structural formation in self-
propagating, high-temperature synthesis systems in
microgravity were established, and methods of synthesizing
highly porous, high-melting, heat-insulating materials with
unique properties were developed. Materials with granular structures and foam materials
based on self-propagating, high-temperature synthesis systems were obtained, and
experiments were conducted to obtain coatings and connections via self-propagating high-
temperature synthesis, SHS welding, and SHS soldering in space conditions.
The results of the studies [SVS-1] and [SVS-2] showed the high gravitational sensitivity of the
processes taking place in the combustion waves and high temperature transformation liquid
phase products. Unique macro and microstructures of cast combustion products and porous
