“…7). In addition, Cu nanoparticles can bear and pass on the stress and therefore make load bearing become more uniform, leading to better friction-reduction and anti-wear performance of the filled oil [35]. It is needed to explain that the synergistic lubricating action of Cu nanoparticles and GO nanosheets is related to the microstructures of the composites.…”

“…The result shows that the tribological properties of base oil can be remarkably improved by addition of serpentine powder under different sliding conditions [6][7][8][9][10][11][12]. Figure 1 shows the tribological properties of lubricant oil before and after addition of serpentine powder [8].…”

Researches on self-repairing material (serpentine phyllosilicate) of our team in the past few years, such as ultrafining treatment, surface modification, self-repairing mechanism, the effect of rare metal on the self-repairing performance of serpentine, were introduced summarily. The phyllosilicate of serpentine shows excellent tribological and self-repairing performance for metal worn surface as additive in lubricant.

“…Similarly, it has been found that the friction force is a function of both velocity and time of contact and that the coefficient of friction may be very low for very smooth surfaces and/or at loads in the micro-to nano-newton range [14,15]. Therefore, some authors have explored lubricants and have proposed them to be potential mediators for reducing friction and wear of the mating surfaces [16][17][18]. However, in applications like automobile engines and complex machinery, the base lubricant is not sufficient to give a long life to the sliding or mating parts.…”

Experimental results of the tribology of aluminum measured with a pin-on-disk tribometer: Testing configuration and additive effects

The friction coefficient, wear rate, and wear coefficient of the aluminum metal surface were measured at room temperature (≈300 K) with a pin-on-disk machine at a fixed load of 196.2 N. Two different testing configurations were adopted: (1) aluminum pin vs. Helix oil-on-steel disk (AHS) and (2) aluminum pin vs. 10% Polytron plus 90% helix oil-on-steel disk (APS). In the AHS configuration, the wear of the aluminum surface was found to be approximately 70 μm; however, in the APS configuration the wear dropped to 20 μm, revealing a marked decrement of one-third of the wear of aluminum. The volume wear rate of the metal in the unaided Helix oil was estimated to be 1.28×10 -3 mm 3 /min. The additive minimized the volume wear rate of the aluminum metal by orders of magnitude to 6.08×10 -5 mm 3 /min. Similarly, the wear coefficient of the aluminum pin, calculated in the AHS configuration, rendered a value of 1.27×10 -10 m 2 /N. In the APS configuration, the same parameter was 4.22×10 -11 m 2 /N, that is to say, an order of magnitude lower than the preceding value. The observed coefficient of friction for aluminum is 0.012 in Helix oil and falls to a remarkably lower value of 0.004 through the Polytron additive. The experimental findings demonstrate that Polytron additive substantially lessens the wear of the aluminum surface; in effect, the wear coefficient and the wear rate decline linearly. This singularity may be linked to the ability of Polytron to impregnate the crystal structure of the metal due to its ionic character and the consequent adherence to the metallic surface as a hard surface layer.
