摘要
为寻找性能更好的人工髋关节材料副 ,本文实验研究了氮化硅陶瓷自组合摩擦副的磨合性能以及磨合前后的起动摩擦因数和稳态摩擦因数。结果表明 :在一定的条件下 ,通过磨合 ,氮化硅陶瓷摩擦副表面可达到超光洁程度 ,它在水中的摩擦因数和磨损率可变得很小。从摩擦学角度来看 ,氮化硅 氮化硅陶瓷摩擦副有可能作为合用的人工髋节关材料而获得应用。
In order to lood for better ceramic-ceramic combinations for total joint replacements, the running-in property, the start up and steady state friction of silicon nitride against itself in distilled water before and after running-in were investigated. The experimental results indicated that after the running-in, the surfaces of silicon nitride could be polished to be ultra smooth and the friction coefficient of silicon nitride against itself in water could become very small under some test conditions. From the tribological point of view, it is likely that silicon nitride-silicon nitride combination is promising combination for the total joint replacements.
