“…The EDS spectra of worn tracks subject to nano-composite coating and nano-oil showed the presence of Al, as shown in Figure 8 . This is also in agreement with previous investigations about using nanoparticles as Fe, Cu, and Co as nano-additives in the lubricants [47]. The EDS spectra of the worn track, testing with pure nickel and pure oil (without nanoparticles) is also shown in Figure 8(a) for comparison purpose.…”

“…conditions. Similarly, the wear mechanism with various nano-sized particles, including Cu [47], ZnAl 2 O 3 [2] and ZrO 2 [51] have been reported by other researchers. They reported that this is because of the bearing-ball effect of the nanoparticles which reduces the contact between the interacting surfaces.…”

This paper presents research findings on the tribological performance of electrodeposited coatings subject to nano-lubricants with the addition of nano-Al 2 O 3 and graphene and Ni/nano-Al 2 O 3 composite coatings. Electrodeposited coatings were produced by using a pulse electrodeposition method. Tribological experiments were conducted by using a linear reciprocating ball on flat sliding tribometer. Experimental results confirm that the wear and friction resistance properties have been significantly enhanced by doping of nano-effects in the lubricating oil and composite coating. The addition of Al 2 O 3 nanoparticles in the lubricating oil showed the best tribological properties, followed by Ni-Al 2 O 3 composite coatings and nano-oil with graphene. The surface morphology and microstructure of electrodeposited coatings were examined by using a Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS) and X-ray Diffraction (XRD). The wear mechanisms of these coatings subjected to tribological testing were investigated by post-test surface analyses. This research provides novel approach to design durable nano-coatings for tribological applications in various industries such as automotive, aerospace, locomotive and renewable energy technologies.

“…The wear in this case may be attributed to the scuffing damage caused by the adhesive action of the asperities due to the stick and slip behavior of the interacting surfaces (Mordukhovich et al 2013). However, a thin layer in this case can also be observed suggesting the film formation capability of CuO nanoparticles (Padgurskas et al 2013). Figure 7b indicates the enlarged version of the surface damage and layer formation on the worn surfaces.…”

This paper presents an investigation of nanodiamond additives (ND) in combination with copper oxide (CuO) and hexagonal boron nitride (h-BN) particles mixed in PAO (poly-alpha-olefin) oil. The experimentation was performed for a ball on disc configuration using steel/steel contacts in the boundary lubrication regime. The loads were varied from 20 to 100 N and sliding velocity was kept constant at 0.58 m/s. The wear behavior was evaluated using SEM images of the worn-out disc surfaces. EDS analysis of the samples was performed to find out the chemical content of the worn surfaces. Results obtained therein demonstrated that oil containing CuO/ND and h-BN/ND exhibited better frictional and wear characteristics. For CuO/ND containing lubricant, the maximum decrease in friction coefficient is 15.45% in comparison to the CuO oil, whereas for h-BN/ND containing additives the overall decrease is 25.45%. It was observed that the combined effect of CuO/ND and h-BN/ND due to their intrinsic characteristics led to the overall improvement in lubrication properties of the base oil.

“…Therefore, such nanoparticles have the potential to provide suitable wear protection and high load carrying ability. Among the metallic nanoparticles, a number of previous research have reported the wear protection and friction behavior of nanolubricants dispersed with copper nanoparticles [2,[4][5][6][7][8].…”

Abstract-This study compares the antiwear (AW) characteristics of bio-based lubricant by addition of carbon-coated copper nanoparticles with the case of non-coated copper nanoparticles, determining the effect of carbon coating. For wear elemental analysis in controlled engine environment, a four-cylinder motoring engine test rig was used. The results showed that carbon-coated nanoparticles helped in wear protection of engine parts.
