“…A review by Moeinfar et al brings these technologies under one term LAM/LMAM -Laser (Metal) Additive Manufacturing -Laser additive manufacturing (of metals). (Moeinfar et al, 2022;Zhang et al, 2022).) This classification was expanded in other works, for example, Karayel and Bozkurt divide LMAM into LAM and WAAM (Wire-Arc Additive Manufacturing) (Karayel & Bozkurt, 2020).…”

This work is devoted to the study of the progress in various areas of additive manufacturing technology usage - from the first theories of layer-by-layer manufacturing to modern additive manufacturing technologies. Additive manufacturing technologies are some of the most rapidly developing sectors of manufacturing, maintaining significant interest of the scientific community due to the their represent of both an alternative manufacturing method for existing structures, as well as opening up opportunities for the development of new structures with structural complexity unattainable for traditional technologies. During historical review of the development and implementation of various technological processes in additive manufacturing for metals, a gap in compiling a comprehensive picture of the general development of additive manufacturing technologies in metallurgy was discovered. For a better understanding and systematization of knowledge about additive manufacturing, on top of answering a number of common questions about these technologies, an analysis of publicly known knowledge about their historical applications in the leading countries of the world was conducted. A number of additive manufacturing technologies were considered, such as Wire-Arc Additive Manufacturing, Selective Laser Sintering, Selective Laser Melting, Electron Beam Melting, and Laser-Engineered Net Shaping. The study focused on the developments carried out by various countries of the world in the 20th and 21st centuries by scientists from such countries as the USA, the United Kingdom, France, Germany, Japan, Canada, the USSR and others. The main documents for the initial research efforts for each family of additive manufacturing processes and various applications of these technologies - from topography and stereolithography to modern medicine with the aerospace industry ‒ were reviewed; their main findings, breakthroughs and challenges were discussed. An analysis and classification of previous studies that focus on the development of various technological processes and their implementation was carried out. As a result of the analysis, a systematized approach to the creation of a comprehensive scheme for the development of additive technologies related to the development of technologies in various directions was proposed.

“…Yin et al [ 17 ] found that applying a WC-10Co-4Cr coating through a supersonic flame of high-velocity oxygen fuel (HVOF) on INCONEL ® 690 alloy surface improved the wear resistance, decreasing the corrosion rate to seawater. Zhang et al [ 18 ] investigated the subgrain segregation between the dendrite core and inter-dendritic region of INCONEL ® 625 manufactured by wire arc additive manufacturing (WAAM), claiming N(Nb, Ti) precipitates in the inter-dendritic region significantly reinforce the Ni-based superalloy corrosion resistance, fabricated by additive manufacturing (AM). Soundararajan et al [ 19 ] applied the electrochemical nanoindentation (ECNI) method to probe the nanomechanical properties of INCONEL ® 625 under an H 2 environment to predict and prevent embrittlement.…”

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.

“…Hu et al [12] reported the influence of Laves phase on the mechanical properties and corrosion resistance of Inconel 625, and the high brittleness of Laves phase created cracks. Zhang et al [13] found the sub-grains segregation generated in Inconel 625 during LAM process, and the contents of Nb, Ti and Mo at dendrite nuclei were higher than those at the inter-dendritic structure, which caused localised corrosion. At present, the research on the corrosion mechanism of LAM nickel-based alloys usually focuses on the overall behaviour with the observation of the local corrosion characteristic.…”

The wire beam electrode (WBE) of laser additive manufacturing (LAM) nickel-based alloy was prepared to help study its crevice behaviour and mechanism at different area in the crevice with different size. The results show that the LAM nickel-based alloy with the crevice size of 0.1 and 0.3 mm presents crevice corrosion characteristics at 1 day and 3 days due to the formation of oxygen-concentration cell at the former two cases caused by the difficult migration of oxygen from the outside into the crevice. The corrosion at the middle and inside of the crevice is more serious than the outside, which is reflected by the 29.92% lower contents of O 2− at the inside than that at the outside of the crevice. Locally, inter-phase corrosion appears between the uniform nickel-based alloy matrix and the insoluble oxides at the inside of the crevice.
