Friction-reducing and self-repair effects of TiO2-SiO2 lubricating oil additives combined with nano- sized La2O3-CeO2 and its mechanism were investigated in the paper. The results showed that, with the addition of nano-sized La2O3 or CeO2 into the 400SN base oil which added TiO2-SiO2 lubricating oil additives, the friction could be decreased obviously and the ability of self-repair could be improved, especially, apparent friction-reducing effect should be found in the early stage during the friction and repair period. The reason is contributed to the addition of nano-sized La2O3 or CeO2, which acts as a catalytic promoter to speed up the forming of chemical reaction film on the wear surface, and improves the friction-reducing and self-repair effects of TiO2-SiO2 nano-sized lubricating oil additives.
