The tribological properties of lamellar liquid crystal of OLA/TEA/LP/H₂O system used as a lubricant for aluminum alloy surface was investigated.The structure of lamellar liquid crystal was characterized by ²H NMR and IR techniques.The experiments on the wear scar width and vertical load showed that the lamellar liquid crystal exhibited a higher load carrying capacity than paraffin oil and commercial lithium grease,indicating the lamellar liquid crystal of OLA/TEA/LP/H₂O system could be a good lubricant for aluminum alloy.
