The invention discloses an efficient anti-wear and anti-friction additive and a preparation method thereof, and relates to the technical field of lubricating materials. The additive comprises at least one
metal composite compound, and
metal elements in the
metal composite compound comprise one or a combination of at least two of Ni, Cu, Zn, Ti or Ce; by controlling the
mass ratio of each element, the synergistic interaction is realized; the preparation method comprises the following steps: mixing a metal composite compound, then carrying out ball milling treatment, and then carrying out
calcination and
surface modification to prepare the additive, the additive provided by the invention can form a high-strength protective film on a friction interface through the synergistic effect of a specific metal composite compound, so that the anti-wear and anti-friction performance and high-temperature stability of the lubricating oil are remarkably improved.
