By implanting B+ and O+ ions respectively into polycarbonate (PC) plates, the surface mechanical properties of PC have been improved. Measurement by Nano Indenter II showed that the hardness of samples increas.d.7-25 times than that before implantation; and the modulus of elasticity rais.d.2-5 times. The wear-resistance was tested by ball crusher; the width and depth of the wear-streak decreas.d.by 1/3-1/2 or even more. The structure, deformation and appearance were analyzed by using Micro-FTIR spectra, EsCA method and the steps instrument. These analyses showed that the structure of PC had been modified: a series of new cross-linking yielded, it depends on the Linear Energy Transition (LET) of implanted ions in the high polymer compounds.
