The nano metal powder comprises silicon dioxide, carbon nano tubes, iron oxide, chromium powder and molybdenum powder, and can be rapidly filled in the damaged part of the friction surface of the lubricating oil under the combined action of the nano metal powder and a nano metal powder dispersing agent, so that the integrity and the regularity of the friction surface are ensured, and the lubricating effect can be fully played.
It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. Further, it is intended that the appended claims cover all such variations and modifications as fall within the scope and boundaries of the appended claims or the equivalents of such scope and boundaries.
