摘　　要：将B+和O+离子分别注入到高分子化合物聚碳酸酯(PC)中,PC的表面显微硬度和耐磨性能均得到了较大提高。用纳米硬度计测量注入前后PC的显微硬度,硬度提高了7～25倍。用球盘式磨损实验机测量注入前后PC的耐磨性能,磨痕的宽度比未注入的窄,最窄的磨痕(或最窄处)为未注入磨痕宽度的1/3～1/2。傅里叶变换红外光谱(FTIR)测试表明,注入前后高分子的结构发生了变化。By implanting B+ and O+ ions respectively into polycarbonate (PC) plates, the surface mechanical properties such as hardness and wear-resistance of PC are improved. Measurement by Nanoindenter II shows that the hardness of samples increases 7-25 times than that before implantation. The wear-resistance was tested by ball crusher, and the narrowest width of the wear-streak decreases for 1/3-1/2. The measurement by Fourier Transform Infrared Spectroscopy (FTIR) indicates: the structure of polycarbonate changes after implantation.
