“…The authors of [71] studied alloying Cu substrates with W powder by a high-current pulsed electron beam. The alloying procedure was carried out at 20 and 30 pulses and the results revealed that the highest value of the hardness (38% greater than unalloyed specimen) and enhancement of the corrosion properties were obtained after alloying with 30 pulses.…”

During the last decades, electron-beam treatment technologies (EBTT) have been widely used for surface modification of metals and alloys. The EBT methods are known as accurate and efficient. They have many advantages in comparison with the conventional techniques, such as very short technological process time, uniform distribution of the energy of the electron beam, which allows a precise control of the beam parameters and formed structure and properties of the materials, etc. Moreover, electron-beam treatment technologies are a part of the additive techniques, which are known as modern methods for manufacturing of new materials with unique functional properties. Currently, modern trends in the surface treatment of metals and alloys are based on the combination of electron-beam technologies with other methods, such as thin film deposition, plasma nitriding, etc. This approach results in a significant improvement in the surface properties of the materials which opens new potential applications and can involve them into new industrial fields. This paper aims to summarize the topics related to the manufacturing and surface treatment of metals and alloys by means of electron-beam technologies. Based on a literature review, the development and growth of EBT are considered in details. The benefits of these technologies—as well as their combination with other methods—are extensively discussed.

“…Consequently, it is postulated that addition of aluminum to cupronickel alloys should improve the corrosion resistance due to the possible formation of protective aluminum oxide film on the surface of the material [8][9][10][11]. liquid surface engineering techniques such as surface melting, alloying and cladding, by applying a number of heat sources like laser and electron beams have been successfully used to enhance the surface properties of copper alloys [12][13][14][15][16][17].…”

Surface alloying of cupronickel alloy with aluminum uSing tungSten inert gaS proceSSSurface melting and alloying of Copper-nickel (Cupronickel) alloy by preplacing aluminum powder and using tungsten inert gas process (tiG) in shielded atmosphere of argon gas were investigated. Surface melting resulted in the formation of a fairly porous dendritic microstructure. Surface alloying with aluminum resulted in the formation of al 2 Cu and al 4 Cu 9 intermetallic compounds along with Cu-rich matrix and unstable martensitic structure. Surface melting reduced the hardness from 140 hV 0.1 (substrate) to 70 hV 0.1 , mainly due to the loss of cold work effect of the initial substrate. on the other hand, surface alloyed zone showed a hardness of 300 hV 0.1 , mainly due to the formation of intermetallic compound. tafel polarization results indicated improvement in corrosion resistance of cupronickel alloy after surface melting and alloying.
