低温等离子体改性口腔陶瓷材料的工艺研究

Study on Technological Parameters of Dental Ceramics Modified by Cold Plasma Technique

对目前难于用常规方法改性的口腔陶瓷材料采用低温等离子体技术进行表面改性 ,引入生物活性物质 ,使用光电子能谱测试分析和蛋白吸附等多种检测方法评价了材料改性后的效果 ,筛选出最佳处理工艺参数。研究表明 ,3种材料含氮量均有所增加。

The surface modification using cold plasma technique was introduced to select the best technological parameters of dental ceramics which are very difficultly modified by routine methods. The bioactive substances were led into materials.The effect of modification was estimated by protein absorption and XPS. It shows that the amount of three materials having nitrogen element increases,and the bioactivity of the materials enhances.
