“…Also, electron beam surface hardening can be combined with other methods, such as physical vapor deposition [64], plasma nitriding [34,65], etc. Grumbt et al [64] have studied a duplex treatment Ti 1-x Al x N coatings with subsequent electron beam treatment of steel substrates.…”

“…The authors of [34,65] have studied an electron beam surface hardening of previously nitrogen-alloyed steel. Their results show a significant increase in the microhardness as well as double improvement of the wear resistance.…”

“…Their results show a significant increase in the microhardness as well as double improvement of the wear resistance. The authors of the discussed studies [34,65] claimed that the reasons of these improvements of the functional properties are the refined microstructure consisting of α-solid solution (nitrous martensite) and γ-solid solution (nitrous austenite) and dispersed fine nitride precipitates. Ormanova et al [22] have presented a combined method for surface modification of tool steels, consisting of electron beam hardening followed by plasma nitriding and subsequent electron beam hardening, and the results demonstrate a hardness of 760 HV after the electron beam treatment and plasma hardening.…”

This chapter aims to summarize the topics related to the application of a surface treatment by high energy fluxes (i.e., electron and laser beams) for developing of new multifunctional materials, as well as to modify their surface properties. These technologies have a large number of applications in the field of automotive and aircraft industries for manufacturing of railways, space crafts, different tools, and components. Based on the performed literature review, some examples of the use of laser and electron beams for surface manufacturing (i.e., surface alloying, cladding, and hardening) are presented. The present overview describes the relationship between electron beam and laser beam technologies, microstructure, and the obtained functional properties of the materials. The benefits of the considered techniques are extensively discussed.

“…In the electron-beam hardening process, the heat generated by the e-beam impingement on the surface is used to transform the material phase, which is due to rapid conduction of heat into the relatively cold bulk interior of the material. Dimitrov et al [26] studied the electron-beam treatment of ion nitriding steel and found that the hardness increased. The high hardness is attributed to the refined structure consisting of a-solid solution (nitrous martensite) and y-solid solution (nitrous austenite) and dispersed fine nitride precipitations.…”

Several advances in materials research have been made due to the wide array of tools currently available for the processing of materials: plasmas, electron beams, ion beams and lasers. The area of material science is fortunate to have seen the development of these tools over the years, be it for new bulk materials, coatings or for surface modification. Several applications have benefited and many more will in the future as the properties of the materials are altered on a micro/nanoscale. Currently, several techniques exist to modify the physical, chemical and biological properties of the material surface; however, this review limits itself to surface modification applications using the rapid thermal processing (RTP) technique. First, a brief overview of the existing surface modification methods using the principles of RTP is reviewed, and then a novel method to create micro/nanostructures on the surface using pulsed plasma exposure of materials is presented.

“…Recently, the working technology of high power density heat sources such as electron and laser beams has been developed rapidly and applied in welding, cutting and surface hardening [1][2][3][4][5][6][7][8][9][10]. Their considerable advantages like the high degree of controllability and automation, low part distortion, capability of very selective and precise treatment are also recognized.…”

The effects of electron beam surface hardening treatment on the microstructure and hardness of AISI D3 tool steel have been investigated in this paper. The results showed that the microstructure of the hardened layer consisted of martensite, a dispersion of fine carbides and retained austensite while the transition area mainly consisted of tempered sorbite. Also, the microhardness of the hardened layer on the surface increased dramatically compared to that of base material. Finally, the hardening response of AISI D3 tool steel to electron beam surface treatment is closely related to the scanning speed of the electron beam. r
