What is nanometer rare earth lubricating oil?

Nanoparticles can not only significantly improve the antifriction and wear resistance of base oil, but also significantly improve the bearing capacity of base oil, which has been confirmed by many tribological experiments. The lubrication mechanism of nano-rare earth was also studied. At present, there are mainly the following viewpoints:

1. polishing mechanism

Nano-rare earth plays a micro-polishing role on the surface of the friction pair, making the friction surface smoother, which not only reduces friction, but also reduces the pressure on the contact surface during loading, which can improve the bearing capacity of oil products.

2. Curling mechanism

Nano-rare earth may play the role of "microspheres" in reducing friction and bearing on the friction surface, and spherical nano-lubricant plays the role of micro-bearing, thus improving its lubrication performance.

3. Repair mechanism

The mechanism of nano-rare earth additives is different from traditional additives. Nano-rare earth additives do not sacrifice surface substances, but deposit, crystallize and spread on the friction surface to form a film under friction conditions, so that the wear is compensated and the purpose of wear resistance and friction reduction is achieved to a certain extent.

4. Film forming mechanism

Because of its extremely high surface energy, nanoparticles are adsorbed on the friction surface at the initial stage of friction, forming a physical adsorption film. At the same time, nanoparticles can also react chemically to form a wear-resistant chemical reaction film.

5. Compound action mechanism

When the friction reaction film of nano-rare earth is not enough to bear, nano-rare earth has a very high diffusion ability. During the friction process, nano-particles form a diffusion layer and a diffusion layer with good tribological properties on the metal surface through diffusion and infiltration, and form a solid solution with the matrix components. The lubrication effect of nano-additives under high load no longer depends on whether the elements in the additives are chemically active to the matrix, but to a great extent depends on whether they form diffusion layers and solid solutions with the matrix components.

Compared with traditional lubricants, we believe that the technical breakthrough and product listing of nano-rare earth lubricants will directly subvert the application of traditional lubricants in the industry, and nano-rare earth lubricants will also become a forward-looking industry in the lubrication market as the second generation lubricants.
