Energy, resource saving and environmental safety technology on reduction of friction and wear
Description
The tribological properties of a number of bimetal compounds in ethyl laurate based lubricating compositions have been investigated by commonly used test methods (ASTM D 4172-94, ASTM D 6425-99). The additives developed ensure great reduction of friction coefficient and the size of wear scars in comparison with pure base fluid.
Surface and near-surface layers of friction zones of specimens have been investigated. The penetration of additive metals into the friction body to a depth of up to 750 nm in concentrations comparable with the percentage of chromium, alloying component of steel; nanostructures with antiwear properties are formed in the near-surface layer.
Innovative Aspect and Main Advantages
- The model lubricating compositions created are eco-friendly:
- The base fluid is based on renewable raw materials of vegetable origin.
- The additives contain no environmentally hazardous constituents; they are complexes of bimetals with polydentate organic ligands, structural analogs of compounds that occur in vivo.
- Great reduction of wear, which is due to the tribodiffusion modification of the metal matrix under friction surfaces by the action of complexes-additives.
Areas of Application
On the basis of the model lubricating compositions investigated, marketable eco-friendly biobased lubricants can be created.
Tribodiffusion modification of a metal matrix under wear track.
Stage of development
The technology has been checked by laboratory tests. PCT application documents have been prepared for filing to a patent agency.
The team of researchers took part earlier in the development and commercialization of additives to lubricating compositions for helicopters.
Earlier, the research was supported by the Department of Power by a letter of suppor
