中文摘要:
      在Tween-80/C10 H21 0H/H20体系层状液晶中合成出平均粒径为30 - 40nm的CaC03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/Cio H21 0H/H20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:CaC03纳米粒子能提高Tween-80/Cio H21 0H/H20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。
英文摘要:
      The nano-particles CaC03 was prepared in Tween-80/C10H2IOH/H20 lamellar liquid crystal. The average particle diameter of CaC03 nanoparticle was about 30- 40 nm. The friction and wear behaviors of CaC03 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 CaC03 nanoparticles in lamellar liquid crystal can improve the tribological properties of Tween-80/C10H210H/H20 lamellar liquid crystal. Tribochemical reaction film is generated during the friction process.
