In this paper, Cr coatings were prepared onto AISI 1045 steel substrates using medium frequency magnetic sputtering process, and were analyzed using the X-ray diffraction (XRD). Five kinds of lubricants were chosen and evaluated as lubricants for Cr coatings/AISI 52100 steel contacts at room temperature. The tribological properties of the lubricants were investigated using a ball-on-disk type UMT reciprocating friction tester. The results indicated that the 1-ethyl-3-hexylimidazolium hexafluorophosphate (L-P206) ILs has excellent friction-reducing properties, the friction coefficient kept at a relatively stable value of 0.036, however pure liquid paraffin has the lowest wear volume value. The Cr coatings using different lubricants show different tribology properties. The worn surfaces of Cr coatings were observed and analyzed using a scanning electron microscope (SEM).

POSS based nanohybrids were prepared via “thiol–ene click” reaction. As a novel additive, they are effective for improving the tribological properties at rather a low concentration when compared with pure solid or liquid lubricating additives.

Purpose – The purpose of this paper is to synthesize oil-soluble copper (Cu) nanoparticles modified with free phosphorus and sulfur modifier and investigate its tribological properties as environment-friendly lubricating oil additives. Design/methodology/approach – To improve the anti-oxidation properties of these nanoparticles, two kinds of surface modifiers, oleic acid and oleylamine were used simultaneously. The morphology, composition, structure and thermal properties of as-synthesized Cu nanoparticles were investigated by means of transmission electron microscopy, X-ray powder diffraction, Fourier transform infrared spectrometry and differential thermal and thermogravimetric analysis. The tribological properties of as-synthesized Cu nanoparticles as an additive in liquid paraffin were evaluated with a four-ball friction and wear tester. Findings – It has been found that an as-synthesized Cu nanoparticle has a size of 2-5 nm and can be well dispersed in organic solvents. Tribological properties evaluation results show that as-synthesized Cu nanoparticles possess excellent anti-wear properties as an additive in liquid paraffin. The reason lies in that as-synthesized surface-capped Cu nanoparticles are able to deposit on sliding steel surface and form a low-shearing-strength protective layer thereon, showing promising application as an environmentally acceptable lubricating oil additive, owing to its free phosphorus and sulfur elements characteristics. Originality/value – Oil-soluble surface-modified Cu nanoparticles without phosphorus and sulfur were synthesized and its tribological properties as lubricating oil additives were also investigated in this paper. These results could be very helpful for application of Cu nanoparticles as environment-friendly lubricating oil additives.
