“…Hasanabadi et al [2] investigated the deposition of Fe48Cr18Mo7B16C4Nb7 crystalline alloy on 316L stainless steel substrate. Xie and Wang investigated the ESD of several Ni-based super-alloy systems [28,29], assessing the feasibility of repairing nickel based super-alloy substrates with MCrAlY deposition. Unfortunately, to date, the state of art is very poor of studies regarding the use of ESD technique to deposit thermally sensitive materials such as the 2024 alloy.…”

ElectroSpark Deposition (ESD) is a pulsed micro-welding process that is capable of depositing wear and corrosion resistance deposit to repair, improve, and to extend the service life of the components and tools. Major new applications have taken place in gas turbine blades and steam turbine blade protection and repair, and in military, medical, metal-working, and recreational equipment applications. In this study, the ESD technique was exploited to fabricate 2024 aluminum alloy deposit on a similar substrate. The deposits were deposited using different process parameters. Heat input was varied on three levels. The outcoming microstructure was analyzed by optical and scanning electron microscopies. The deposit was characterized by the overlapping of layers with a mixed microstructure. The average hardness was independent from the process parameters. Both porosity inside the deposits and cracks at the deposit/substrate interface were detected. The porosity lowered with the heat input and increased the average length of cracks.

“…Novel ceramic candidates, such as La 2 Zr 2 O 7 with pyrochlore structure [3,4] and La 2 Ce 2 O 7 with fluorite structure have been investigated [5]. Also, new processing technologies, such as electrospark deposition, have been used for depositing MCrAlY coatings with high density and good homogeneity [6,7].…”

“…At the initial oxidation stage, it is deemed that the formation of -Al 2 O 3 and ␣-Al 2 O 3 occurs simultaneously [11,14,15]. The fast-growing ofAl 2 O 3 can explain the higher oxidation mass gains of the coating samples.…”
