Experimental investigation of the material surface modification in microsecond plasma opening switch

This paper is devoted to the investigations of the material surface modification by high power ion beam generated in microsecond plasma opening switch properties (MPOS). The various types of steels have been investigated: stainless steel 17-4PH, carbon steel C1020, pure iron. For all these materials the optimal regimes for irradiation were defined. The significant increasing in microhardness was obtained for these materials (1.5 ÷ 2 times). The numerical calculations and theoretical estimations of the ion beam-matter interaction have been performed also. The advantages and problems of this approach are considered.
