Description

Complex oxides Sr0.14Ca0.86CuO2, SrCuO2, and CaCuO2 were prepared from SrCO3, CaCO3, and CuO by sintering method. The powered complex oxides were added to three paraffnic base oils having different viscosities, and their lubricities in oil boundary lubrication were evaluated using a Falex-type tribometer.<br>When the se complex oxide powders were added to the base oil of very low viscosity, they improved the lubricity of the base oil even with addition of low concentration (2-5mass%). Furthermore, these lubricities were enhanced by using the base oil and oleic acid together as an oiliness agent and dispersant. Especially, Sr0.14Ca0.86CuO2 having an infinite layer structure indicated better friction properties and also better wear resistance even by using it together with oleic acid and the low viscosity base oil.
