“…The results revealed that the EBT of the Ti-based alloy led to an increase in the surface roughness, from 8 nm to 25 nm and a slight decrease in the hardness, from 7 GPa to 6 GPa and reduced coefficient of friction. The same authors [44] mentioned that the increase in the surface roughness led to less colonization of the surface by bacterial cells than the conventional fabricated surfaces. Furthermore, the obtained values for the hardness after the EBT of the substrate are closer to that of the human bones and the severe stress-shielding effect after implants insertion into the body could not be expected.…”

Petrov et al [44] studied the effect of electron-beam treatment of Ti5Al4V alloy on the phase composition, surface topography and mechanical properties of a bilayer TiN/TiO2 coating deposited by reactive magnetron sputtering. The results revealed that the EBT of the Ti-based alloy led to an increase in the surface roughness, from 8 nm to 25 nm and a slight decrease in the hardness, from 7 GPa to 6 GPa and reduced coefficient of friction.…”

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.

“…The roughness of TiO 2 dielectric surface-induced electrostatic potential, which was capable of varying the molecular genetic features and viability of leukemia T-cells via mechanisms discrete to ROS generation. Our research group found out that electron beam surface treatment of titanium alloy not only increased the surface micro-and nano roughness [128] but also decreased the surface hardness of the magnetron sputtered TiN with overlaying TiO 2 coating bringing it closer to that of trabecular bone and human teeth and decreasing the elastic modulus mismatch between the bone and implant [129]. Moreover, nanostructured arc PVD deposited TiN with overlaying glow-plasma discharge deposited TiO 2 coating indicated an increase in MG63 cell viability by almost 100% after 24 h relative to the bare Ti6Al4V alloys [130].…”

This literature study is based on the research work conducted in the field of erosion behavior of steel alloys. The focus is on the surface modification of the steel alloys by heat treatment, surface hardening and surface coating methods. Laser cladding and laser hardening processes are also explained. The influence of tribological parameters on the erosion is explained. Steel alloys are chosen because of a wide number of applications due to their excellent properties. Efforts have been made to understand the cause and the remedial action towards the improvements in wear performance. Suitable surface treatment method on the steel alloys may definitely do this work but there should be a need of proper control over the process parameters. The environmental conditions of the laboratory are differing from the real working environment. Hence, the results which are satisfactory at the laboratory are not doing well in real place of application.
