Evaluation the structure transformation of intermetallic feal powder particles in gas detonation spraying process (GDS) to the water
Abstract
<p>The scientific objective of the paper is a complex analysis of structural changes in FeAl feedstock powder due to heat take-over by FeAl powder particles in a flow of detonation gas products in the conditions of controlled GDS process during spraying into the water. Analysis of SEM/EDS/EBSD and XRD structural interdependences identified will allow to judge the issue of the state of the FeAl particles during the impact with the substrate which is crucial for the formation of the intermetallic, multifunctional structure of the FeAl protective coating with promising exploitation properties for the power plant industries. Experimental verification of the microstructure assumptions was based on the results of structural studies of the sprayed FeAl particles (chemical and phase composition, crystallographic and morphological micro-texture, as well as FeAl superlattice inheritance from the powder particles). Estimated properties for heterogeneous, multi-phase intermetallic structure will be a foundation for the Fe-Al intermetallic composite structures.</p>
