THE FORMATION OF STRENGTHENING COATS BY MICROSECOND DURATION HIGH-CURRENT RELATIVISTIC ELECTRON BEAM

The method of remote drawing of strengthening coats by means of a high-current microsecond duration relativistic electron beam is developed. Experiments were performed using pulse electron accelerator TEMP-A in a single pulse generation regime. Parameters the REB were as follows: current 1...5 kappa A, electron energy up to 0.5 MeV, a pulse duration 2...5 mu s, a power density up to 5.10(12) W/m(2). The method consists in drawing of materials layer molten by electron beam on a cold substrate. With this melting of material occurs at some distance from a substrate that provides the melt's acceleration in a direction of a substrate and it melting away. The material of a coat immix with a material of a substrate and therefore initiate the corresponding chemical response in specific conditions of high pressure and temperatures that provides formation of coats with given in advance properties.
