Abstract
In this study we report hardness changes and structural effects in the polymer Cr-39 following implantation with 50-keV hydrogen and argon i ons to doses between 1 x 10(15) and 2.8 x 10(17) ions/cm(2). An increa se in hardness (maximum contact pressure) was observed following both H and Ar implantation, with increases by factors of 6.5 and 1.5, respe ctively, Significant compaction of the ion beam modified layer was als o observed for both ion species. These results suggest that the bondin g changes induced by H implantation, which is dominated by electronic stopping processes, are more effective at enhancing the hardness of CR -39 than Ar implantation, which has considerable nuclear as well as el ectronic stopping,
