中文摘要：
用能量为110keV剂量分别为1×10^14ions／cm^2、5×10^14ions／cm^2,2.5×10^15ions／cm^2和1.25×10^16ions／cm^2的质子对聚酰亚胺进行注入改性。摩擦磨损试验表明，质子注入能够提高其耐磨性。但在不同载荷下，其摩擦磨损行为随着注入剂量的变化有所不同。未注入样品的磨痕内存在明显的粘着和划痕，而注入之后，粘着和划痕受到抑制．磨痕变得光滑。
英文摘要：
The polyimide was implanted with 110 keV protons in four doses of 1 × 10^14 ions/ cm^2, 5× 10^14 ions/cm^2, 2.5× 10^15 ions/cm2 and 1.25 × 10^16 ions/cm^2. Friction and wear experi- ments showed the improvement of their wear-resistance after proton implantation. But under different loads, the variety of their friction and wear behavior with implantation doses showed some differences. There were obvious adhesiveness and scuffing in the wear scar of polyimide before implantation, whereas the wear scar became smoother after implantation, with the adhesiveness and scuffing abated.
