金刚石研磨膏

结果表明，通过数控车床车削、SiC超细粉和金刚石研磨膏分级抛光并用特制工具修正其尺寸，可以得到具有一定表面光洁度并与股骨柄配合良好的Al2O3陶瓷髋关节股骨头假体。

The results showed that after being processed on numerical control lathe , grade polished by SiC micro-powder and diamond abrading agent and size corrected by special tools , the Al_2O_3 ceramic hip joint femur ball has good surface degree of finish and it matches well with the femur handle .

用于预处理的金刚石研磨膏的粒度不同，影响金刚石薄膜沉积时的形核密度、晶形和薄膜的质量；

The grain size of diamond abrasion paste significantly affected the nucleation density and the crystal morphology of the diamond films .

实验表明，对基片进行适当的预处理，包括用金刚石研磨膏仔细研磨和沉积前原位沉积一层无定形碳层，可显著提高成核密度；

It showed that proper pretreatments , such as polishing substrate surface carefully and in situ pre depositing an amorphous layer on the alumina substrate surface , would enhance nucleation of diamond obviously .

在沉积实验之前，首先用细砂纸将硅片打磨5分钟，金刚石研磨膏研磨硅片15分钟，用去离子水冲洗，超声波清洗，取出后吹风机烘干，然后放入反应室沉积金刚石薄膜。

Before the experiment , the thin sand paper was first employed to nick the wafer for 5 minutes . The diamond abrasive abraded the wafer for 15 minutes . Then the wafer was cleaned in the deionized water by the ultrasonic and was dried by the blower .
