摘要
在Tween-80／C10H21OH／H2O体系层状液晶中合成出平均粒径为30～40nm的CaCO3纳米粒子，用四球磨损试验机考察了CaCO3纳米粒子作为润滑添加剂在Tween-80／C10H21OH／H2O体系层状液晶中的摩擦磨损行为，并用X射线光电子能谱对其抗磨减摩机理进行了研究。研究结果表明：CaCO3纳米粒子能提高Tween-80／C10H21OH／H2O体系层状液晶的摩擦学性能，在摩擦过程中，摩擦表面生成了化学反应膜。
The nano-particles CaCO3 was prepared in Tween-80/C10H21OH/H2O lamellar liquid crystal. The average particle diameter of CaCO3 nanoparticle was about 30- 40 nm. The friction and wear behaviors of CaCO3 nanoparticles as an additive in lamllar liquid crystal were investigated with four-ball machine. Anti-wear and reducing friction mechanism were analyzed by X-ray photoelectrons Spectrum（XPS）. It has been found that the CaCO3 nanoparticles in lamellar liquid crystal can improve the tribological properties of Tween-80/C10H21OH/H2O lamellar liquid crystal. Tribochemical reaction film is generated during the friction process.
