Investigations of mechanical and tribological properties of Be and R6M5 instrument steel, exposed to intense-pulsed ion beams with short pulses (∼10 −8 s), middle intensities (∼10 8 W/cm 2 ) and energy fluences (1–6 J/cm 2 /pulse) are described. Hardening has been observed not only in near-surface layers, but also at high depths in irradiated target, which were one or two orders more than ion beam range. This was mostly connected with an increase in dislocation density. Abrasive wear was judged from mass ablation rate per unit time and its distribution over the depth correlated closely with the magnitude of microhardness. We found an increase in wear resistance under dry friction conditions. A possible industrial application of this effect is discussed. |
