Formation of Fe–Al intermetallic coating on low-carbon steel by a novel mechanical alloying technique

Combining equal-channel angular pressing and heat treatment to obtain enhanced corrosion resistance in 6061 aluminum alloy

“…For instance, the corrosion behavior of copper does not qualitatively change after ECAP [27]. However, the microstructural evolution during severe plastic deformation may lead to enhanced stability and homogeneity of coating [28,29]. The state of grain boundary, which depends on the pre and post ECAP heat treatment, is also another important factor.…”

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

“…The SEM image also shows that no crack is found at the coating interface, suggesting a good bonding between FeAl coating and low carbon steel. The collisions between ball, substrate and powder during coating process lead to better particle contact with a substrate [19]. EDX elemental maps as shown in Fig.…”

“…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. Zhan et al [17] show the formation FeAl layer during the deposition of Al coating on low carbon steel.…”

Chemical Vapor Deposition of Al13Fe4 Highly Selective Catalytic Films for the Semi‐Hydrogenation of Acetylene

“…Several studies have been reported on the formation of intermetallic phases in the Al–Fe system . Various deposition techniques have been applied to obtain Al‐Fe intermetallic coatings, including thermal spraying and magnetron sputtering or mechanical alloying . Despite the effective production of Al‐Fe intermetallics, these methods suffer a number of drawbacks, such as the swelling phenomenon because of rapid and violent phase transformations during sintering, or technical difficulties related to considerable differences of properties of the substrate and the coating materials (e.g., their coefficient of thermal expansion and reactivity resulting in a poor interfacial adherence).…”
