| Abstract: |
| 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. |
