High-power pulsed ion beam modification of the surface properties of alumina ceramics

Influence of a high-power pulsed ion beam on the mechanical properties of corundum ceramics

“…In the selection of irradiation modes it is possible to achieve hardening of ceramics. This result is confirmed by the data of paper [23]. Figure 3.…”

“…The use of ceramics with gradient properties has great prospects, when the surface layer differs in its characteristics from the corresponding parameters of the bulk layers. As shown in works [11][12][13][14][15][16][17][18][19][20][21][22][23][24], surface treatment can be effectively carried out using low energy high current pulsed electron beam (LEHCPEB) [11][12][13], laser treatment [14,15] and high-power pulsed ion beam (HPPIB) [16][17][18][19][20][21][22][23][24]. To study thin modified layers of dielectrics, the method of secondary ion mass spectrometry [25][26][27] and the Rutherford backscattering method [28,29] have proved to be very useful.…”

“…They allow to carry out high-precision treatment of complex shaped ceramic parts with a short exposure time to the surface, are equipped with simple process automation, etc. Among radiation methods of influence on materials, the method of surface modification by highpower pulsed ion beams (HPPIB) [16][17][18][19][20][21][22][23][24] widely is used.…”

Effect of Gamma Irradiation on the Electrical Properties of Vitreous SiO2

“…Radiation damage in dielectric materials, including ceramics and glasses, has been the subject of many studies [1][2][3][4][5][6][7][8][9]. Comparatively little data have, however, been reported on glassy materials, even though these are being used increasingly in many technological applications.…”

“…Oxide dielectrics, e.g., Al 2 O 3 and SiO 2 , are the basic components of ceramics, many optical, electronic, structural, and laser materials, and MOS structures [1][2][3][4]6]. They are widely used in various fields of science and technology.…”
