Abstract
In this paper energetic ion beams of a 90 kJ filippov type plasma focus were utilized to irradiation aluminum samples. The working gases were pure D2, and D2+Kr2%. The phenomena of melting, micro cracks, evaporation, and sputtering of the surface layer have been noticeable on the samples. Surface smoothing was remarkable when a heavy rare element added to D2. Adding Kr to the D2 filling gas lead to collapsing bubbles and greater surface damage. Micro hardness of surface layer tends to decrease particularly in the central region of the sample where destruction is more intense. The decrease in micro hardness for D2+2%Kr is more than that compared to deuteron ion treated sample.
