“…Moreover, the porosity induced by some INCONEL ® alloy processing also contributes to a significant decrease in toughness and fatigue resistance, facilitating crack generation and However, this property makes INCONEL ® alloys a hard-to-machine-metal [10] and difficult-to-metal-shape substance, influencing heat distribution during machining and impacting the surface quality when employing conventional chip-start cutting machining and surface treatment techniques [11]. Conventional manufacturing (CM) and the instantaneous work hardening in the chip formation region due to the creation of a surface with several porosities make INCONEL ® alloys prone to reduced low-cycle fatigue (LCF) strength [12] and corrosion, leading to faster oxidisation by ammonium chloride (NH 4 Cl) [13], H 2 embrittlement in electrolysis processes environments [14,15] and sulphuration corrosion failure [16]. Both work hardening and H 2 embrittlement induce increased hardness, which, in turn, induces a decrease in toughness and fatigue resistance.…”

Build-up-edge (BUE), high-temperature machining and tool wear (TW) are some of the problems associated with difficult-to-machine materials for high-temperature applications, contributing significantly to high-cost manufacturing and poor tool life (TL) management. A detailed review of non-traditional machining processes that ease the machinability of INCONEL®, decrease manufacturing costs and suppress assembly complications is thus of paramount significance. Progress taken within the field of INCONEL® non-conventional processes from 2016 to 2023, the most recent solutions found in the industry, and the prospects from researchers have been analysed and presented. In ensuing research, it was quickly noticeable that some techniques are yet to be intensely exploited. Non-conventional INCONEL® machining processes have characteristics that can effectively increase the mechanical properties of the produced components without tool-workpiece contact, posing significant advantages over traditional manufacturing.

“…Rich in nickel, this alloy features a single austenite structure, which enables good resistance to stress corrosion caused by chloride ions. The substantial amount of chromium significantly promotes its resistance to sulfide stress corrosion cracking and high-temperature oxidation [6,7]. This alloy is extensively applied in steam generators and chemical containers and the former have particularly higher requirements for material performance.…”

In this study, Cr3C2-Al2O3-NiCr coatings were prepared on INCONEL 600 alloy surfaces using the supersonic flame spraying technique, followed by a laser remelting treatment. In this way, this study further explored what impacts laser remelting has on coating performance. To this end, optical microscopy (OM), scanning electron microscopy (SEM), and electron backscatter diffraction (EBSD) were employed to carry out microstructural characterization. Energy-dispersive X-ray spectroscopy (EDS) was applied to conduct an analysis of the coatings’ elemental distribution while X-ray diffraction (XRD) was used to determine the coating phases. To measure the microhardness of the coatings, a microhardness tester was applied. In addition, the study investigated the samples’ electrochemical corrosion resistance and friction-wear performance under different surface conditions. According to the results, laser remelting enhanced the coating density, improved metallurgical bonding with the substrate, and optimized the carbide distribution, thereby enhancing corrosion and wear resistance in both air and corrosive media. However, excessive laser power hinders Cr3C2 nucleation, leading to diminished coating hardness and wear resistance in Cr7C3 formation.
