Microstructure characterization of D-gun sprayed Fe–Al intermetallic coatings

Processing conditions, microstructure and mechanical properties of hetero-nanostructured ODS FeAl alloys produced by spark plasma sintering

“…They include for example heavy deformation [2,3] and consolidation from a nanostructured milled powder by using conventional hot compaction [4,5] or rapid sintering techniques authorizing to retain the fine structure present in the powder. The latter consists of thermal spraying by different processes such as high velocity oxy-fuel (HVOF) [6][7][8], atmospheric plasma spraying (APS) [9], detonation gun [10], arc and cold spraying [11,12] as well as the electric field assisted spark plasma sintering (SPS) [13][14][15].…”

Gas detonation spray forming of Fe–Al coatings in the presence of interlayer

“…When the technological parameters of the GDS were considered [17] the research proved that even insignificant changes in one of the parameters of spraying (the volume of fuel gas, oxidant, carrier gas, the spraying distance or frequency of spraying) considerably influence the value of kinetic and thermal energy of the process which are decisive factors for the quality of the gas detonation sprayed coatings.…”

“…Current adhesion strength tests of the Fe-Al coatings deposited onto 1045 steel substrate, the TAT (Tensile Adhesion Testing), shows the adhesive strength at maximum 37 MPa [17].…”

Structure and high temperature oxidation of mechanical alloyed Fe-Al coating

“…Many studies were conducted to develop Fe-Al coating with different methods, such as cold spraying [7], thermal spray [8,9], hot dipping [10], high-energy micro-arc alloying [5], laser surface alloying [11] and plasma spraying [12]. In recent years, the mechanical alloying technique has been used to deposit multi-component structures, such as Ti-Al coatings [13], Al coating [14], TiN coating [15] and Cr coating [16] on different substrates.…”
