Thermo-phisical properties of multiphase Fe-Al intermetallic coating with the oxide ceramics created insitu during gas detonation process

The scientific objective of the work is analysis of the thermo-physical properties of the multi-phase structure in Fe-Al intermetallic coating with the oxide ceramics, created in situ as the result of cyclic interactions of two phase metallizing flux during the GDS process. Literature data of the Fe-Al intermetallics concerns only on the mono phase materials, which thermo-physical properties are not so strongly dependent on the structural composition, formed during given „thermal history” in the GDS conditions. Estimated in the principal research basic thermo-physical properties for heterogeneous, multi-phase intermetallic coatings structure will be a foundation for the Fe-Al intermetallic composite structures design applied as protective coatings deposited by supersonic metalization stream. Estimation of the Young's modulus at temperature to 1000 ^oC, diffusion, expansibility and specific heat of the intermetallic structures with the oxide ceramics are key factors for analysis of the properties of the GDS coatings.
