The "(Ti) film/(В4С ceramics) substrate" system was investigated after irradiation by an intense pulse electron beam. It was found that the multiphase structure crystallized on the eutectic reaction was formed in the surface layer of the film/substrate system. It was shown that high-speed metallization of the surface layer in the В4С ceramics leads to increase of its fracture toughness.

Experimental investigations have been carried out to determine structural and phase transformations of a surface layer in SiC ceramics samples irradiated by an intense pulse electron beam of submillisecond duration. It was shown that electron beam modification of the surface layer of the SiC ceramics was followed by improvement of mechanical characteristics of the material. The suggestions have been made to explain this effect.

Good Agreement

The paper presents measurements taken with a high-speed infrared pyrometer for the surface temperature of VT1-0 titanium alloy during pulsed electron beam irradiation at different pulse energy densities. Also presented are numerical simulation data on thermal fields for the same conditions, showing a good agreement with the measurements. The results demonstrate that the heating rate of the VT1-0 surface depends on the main beam parameters, and its solidification occurs at a temperature ≈ 280 °C lower than the melting point.

The doping of the surface layer of titanium by the yttrium, oxygen and carbon was implemented. Irradiation of the doped layer by intense electron beam leads to the formation of the multiphase structure and the nanosubmicron range having a high microhardness (at 3-fold higher than the hardness of the original structure) and a low coefficient of friction (6 times lower than the friction coefficient of the starting material).

AbstractHigh speed framing camera (HSFC) could be used to capture the image of the electron beams generated by the intense electron-beam accelerator (IEBA), and it is useful to visualize the evolution of discharging and plasma generation phenomenon. So an overview of the application of HSFC on the IEBA is presented. First, we introduce the synchronization problem of HSFC and IEBA, and a synchronization trigger system which could provide a trigger signal with rise time of 17 ns and amplitude of about 5 V is presented. Second, an imaging system based on IEBA, HSFC, and the synchronization trigger system is developed, and it can be used to image the developmental process of plasma in the output vacuum chamber of IEBA and to measure the electrical parameter of IEBA and electrical trigger signal in real time. Furthermore, the imaging system is used to investigate the developmental process of the electron beam of the A-K gap in vacuum under 180 nanosecond quasi-square pulses. It is obtained that the short A-K gap is closed prematurely under long pulse operation with plasma expansion velocity of about 6.25 cm/µs and the light emission in the A-K gap region has the characteristics of “re-ignition” with light duration time about 3800 ns. At last, the discharging process of surface flashover channel of poly-methyl methacrylate (PMMA) insulator with gap spacing of 170 mm in vacuum under nanosecond quasi-square pulses is studied by the imaging system, and the change of luminosity is analyzed during the surface flashover process.
